ZWED0006W​
RBAC is disabled in the configuration. All authenticated users will have access to all services. Enable RBAC in the configuration to control users' access to individual services.
Reason:
RBAC can be used to permit and reject access to each URL of the app-server individually according to security rules such as those from SAF resources. Enabling RBAC is beneficial but requires configuration first so this message is often seen.
Action:
If you wish to learn more about RBAC and enable it, read Application Framework Advanced Configuration
ZWED0007W​
Dataservice authentication definition is not present in server configuration file, or malformed. Correct the configuration file before restarting the server.

If you were doing a configuration change, you should try again or restart the server if the error persists. You can check the error to see the reason for the issue.
ZWED0016W​
Error setting override: error
Reason:
The server attempted to load a new configuration, but failed when writing the configuration update to a file.
Action:
Check the error to see the possible cause for the failure. Retry this operation but if the issue persists you should restart the server.
ZWED0017W​
Duplicate plugin identifier pluginId found.
Reason:
A plugin was trying to be added to the server but it wasn't possible because another plugin with the same ID was already running within the server.
Action:
Plugin upgrades cannot be done through the add plugin operation. Instead, the server should be stopped to perform this upgrade.
ZWED0018W​
Could not initialize Java manager. Java services from Apps will not be able to load stackTrace
Reason:
The Java manager is used to run Java services bundled into plugins. It could not start, so the server cannot load any Java services. Plugins that have Java services may fail to load, but the server will still run with the remaining plugins.
Action:
Check the stackTrace output to determine the reason the Java manager could not run.
ZWED0019W​
Exception when setting log level for ID=logId. E: stackTrace
Reason:
Log levels listed in the configuration file are set during startup. For some reason, the level for logId could not be set, but the server will continue to run with that logger set to default verbosity.
Action:
Check the stackTrace to determine the reason why logId could not be set. Potentially the log id was an invalid name, or the log level was an invalid number.
ZWED0020W​
Could not spawn childProcess: errorMessage
Reason:
The child process that was requested to run when the server started up could not run for some reason. childProcess lists the parameters requested to start the process.
Action:
Check the errorMessage to determine the reason of failure, and also verify that the information in childProcess is valid.
ZWED0021W​
Missing one or more parameters required to run. The server requires either HTTP or HTTPS. HTTP Port given: httpPort. HTTPS Port given: httpsPort HTTPS requires either a PFX file or Key & Certificate files. Given PFX: pfx Given Key: key Given Certificate: certificate config was: configuration All but host server and config file parameters should be defined within the config file in JSON format.
Reason:
The server could not start because the configuration was not valid. When the server's HTTPS section is specified, httpsPort must be a valid TCP port number and you must have a key and certificate. If the HTTPS section is not specified, the HTTP section must be specified and httpPort must be a valid TCP port number.
Action:
Review the configuration to see if there are corrections to be made before restarting the server.
ZWED0027W​
Plugin (pluginId) loading failed. Version: versionNumber. Message: "errorMessage" Successful: percentSuccess% (pluginsLoaded/pluginsTotal) Attempted: percentAttempted% (pluginsAttempted/pluginsTotal)
Reason:
An error prevented the plugin pluginId from loading. Other plugins will still be attempted to be loaded, until percentAttempted reaches 100%. The server will run if all auth plugins needed have successfully loaded.
Action:
Review errorMessage to see if there is something you can do to fix the error. You may need to contact the plugin developer to find a solution. If you do not need this plugin, it is OK to continue.
ZWED0028W​
Encountered parse exception while reading filename
Reason:
The server cannot read the JSON file filename. This might be a configuration file or a plugin file. In either case, the server may not be able to run or may run with less plugins than desired.
Action:
Review the file listed in filename. Check if it is in the right encoding for your platform. Tagging the file according to its encoding is recommended for z/OS. Also check if the file is valid JSON. The file may have a missing or extra comma, or missing quotes or brackets.
ZWED0029W​
Authentication plugin was found which was not requested in the server configuration file's dataserviceAuthentication object. Skipping load of this plugin
Reason:
The server will attempt to load every plugin given to it in the plugins directory. Authentication plugins are only needed if a plugin requests them or it implements the default authentication category. Because the server did not find a user of this plugin, it was not loaded.
Action:
No action is needed unless you believe that this plugin needed to be loaded. If so, check for plugins that require it to determine if there is missing or incorrect auth configuration.
ZWED0030W​
location points to an invalid plugin definition, skipping
Reason:
The file specified at location is not valid according to the pluginDefinition schema, so it cannot be loaded. The server will still start without the plugin if possible.
Action:
Correct the pluginDefinition.json file of the plugin to load the plugin on next server restart, or remove the plugin if not needed.
ZWED0032W​
Failed to load filename
Reason:
The plugin definition located at filename could not be read, so the plugin that referred to this cannot be loaded. The server may still run without the plugin if possible.
Action:
Check if the file exists and is readable to the user that is running the server. Also check that the file is in the right encoding for the OS the app-server is running on. On z/OS, it is recommended to have the file encoding tagged.
ZWED0033W​
Could not initialize plugin pluginId: error
Reason:
The plugin pluginId could not be loaded. This may be due to unsatisfied imports, where an import requested a version of something that was not available, or an entire plugin was not available. The server will still attempt to load if this plugin was not needed.
Action:
Check the error message to determine the cause of error for correction.
ZWED0034W​
Skipping install of plugin due to existing plugin with same id=identifier
Reason:
The plugin could not be loaded due to a plugin that is already loaded containing the same identifier ID. Plugin IDs are unique, so the first plugin with that ID that is seen is the one that is loaded.
Action:
Check to see if you have 2 extensions that contain plugins with the same ID. Alternatively, an extension may have updated to have its name change without its ID changing, causing a duplicate to appear. You may need to clean up your extensions or the contents of the pluginsDir directory.
ZWED0035W​
Error thrown when installing plugin=identifier: error
Reason:
The plugin with id identifier could not be added to the server because of an error that occurred. The server will still attempt to run without the plugin if possible.
Action:
Check the error message to see the reason for the error, and correct it before restarting the server in order to try loading the plugin again.
ZWED0036W​
Uncaught exception found. Error: stackTrace
Reason:
The server encountered an unexpected error. If cluster mode is running, this will result in the worker crashing but the cluster starting a new worker to replace it. The client that initiated the request will need to retry the operation though other clients should not experience disruption.
If cluster mode is not running, the process will end but the launcher will restart it. In this case, state may be lost unless the caching service was also being used.
Action:
The stackTrace should be sent to developers so that the issue can be fixed.
ZWED0037W​
Ending server process due to uncaught exception.
Reason:
The server is stopping after encountering ZWED00036W.
Action:
The information within ZWED0036W should be sent to developers so that the issue can be fixed.
ZWED0038W​
Reason:
A child process with path childProcessConfig.path encountered an error with receiving data.
Action:
Action depends on context of what data is. May be useful in debugging an issue with internal ProcessManager.
ZWED0039W​
Exception at server cleanup function: stack
Reason:
An exception occurred when ending process, during the cleanup phase.
Action:
No action is needed, but stack can be sent to developers if server processes are failing to end.
ZWED0040W​
Callservice: Service call to %s:%s%s failed.
Reason:

Rejected undefined referrer for url=originalUrl, ip=ip
Reason:
Throws 403 Forbidden when App server fails to honor a network request due to failed referrer check.
Action:
Double check the address. A possible reason for a 403 error is a misstyped originalUrl or ip or because loopback routing is not configured in the App server.
ZWED0172W​
Rejected bad referrer=referrerHeaderValue for url=accessedUrl, ip=clientIp
Reason:
The client from clientIp tried to access accessedUrl but due to having a referrer header value that didn't seem to originate from this server, a security violation was caused and the attempt to access the URL was rejected.
Action:
Review the values to determine if this was a valid attempt to access the server or not. If this access seems suspicious, then the server was correct in rejecting the access. However, if the access attempt seemed legitimate, then this points to the referrer configuration needing revision. You can customize which referrer header values are permitted using the environment variable ZWE_REFERRER_HOSTS and it should be set to match the external hostnames of the system the app-server is running on.
ZWED0173W​
Unable to decode P12 certificate (different password than keystore?). Attempting to use empty string as password. Decode error: error.
Reason:
The server tried to load the p12 file provided for the server certificate or certificate authorities, but encountered error. The server may not be accessible as a result of invalid TLS configuration.

Check the value of zowe.certificate.keystore.password and zowe.certificate.truststore.password, or the environment variable KEYSTORE_PASSWORD to see if they are valid for the p12 file provided, and adjust the configuration if needed.
ZWED0174W​
componentName could not verify (operatingSystem) as a supported platform to install (pluginId). Proceeding anyway...
Reason:
The plugin pluginId has a dependency which can only run on certain operating systems, and operatingSystem is not on the list, but because the operating system is not explicitly forbidden, the server will attempt to load the plugin anyway. This may fail, but the server may continue to run without the plugin if possible.
Action:
Review the plugin dependencies as seen in the plugin's pluginDefinition.json file to see if your Zowe configuration or the plugin can be changed in order to match the requirements. Consult the plugin developer if you believe the plugin was able to run fine on the operating system, so they can explicitly add support in the future.
ZWED0175W​
componentName could not verify (systemArchitecture) as a supported architecture to install (pluginId). Proceeding anyway...
Reason:
The plugin pluginId has a dependency which can only run on certain system architectures, and systemArchitecture is not on the list, but because the system architecture is not explicitly forbidden, the server will attempt to load the plugin anyway. This may fail, but the server may continue to run without the plugin if possible.
Action:
Review the plugin dependencies as seen in the plugin's pluginDefinition.json file to see if your Zowe configuration or the plugin can be changed in order to match the requirements. Consult the plugin developer if you believe the plugin was able to run fine on the system architecture, so they can explicitly add support in the future.
ZWED0177W​
Unable to load actionOrRecognizer for 'pluginId' into config
Reason:
The plugin pluginId has an action or recognizer within its package and the plugin install process was trying to copy that into the workspace so it can be used, but encountered an error that prevented this.
Action:
Contact support if the reason cannot be determined.
ZWED0178W​
Skipping authentication plugin pluginId because it's not HA compatible
Reason:
The server is setup for running in high availability (HA) mode which requires that plugins that have state, in particular authentication plugins, must be HA-compatible or else errors will occur. Therefore, the server skips over loading of this plugin nbecause its pluginDefinition.json did not state it was HA compatible.
Action:
Either the plugin must be updated to support and state its support for HA, or it must be removed, or HA mode disabled. To make a plugin support HA, the conformance program should be reviewed. When HA mode is supported, the plugin can be marked as compatible by setting capabilities.haCompatible=true within its initialization.
ZWED0179W​
Unable to retrieve the list of certificate authorities from the keyring=keyringName owner=username Error: error
Reason:
The server could not automatically determine the certificate authorities (CA) from the z/OS keyring listed. This may cause the server to be unable to verify certificate chains from other servers or clients causing other errors later.
Action:
Review the error to resolve it and contact support if needed. It's also possible as a workaround to explicitly state the CAs within the keyring that you would like to load, rather than relying upon the server's attempt to automatically find all CAs within the keyring.
ZWED0001E​
Error: error
Reason:
The server is running in cluster mode and the cluster manager has encountered an unexpected error.
Action:
Review the error to resolve it, and contact support if needed.

ZWED0003E​
Loopback configuration not valid, loobackConfiguration Loopback calls will fail!
Reason:
The loopback configuration that the server uses to contact itself over an internal network was missing a value for the network port, therefore no requests over the loopback address will be possible.
Action:
Review the configuration of components.app-server.node.port to see if it has a value and set one to fix the issue.
ZWED0004E​
Could not listen on address ip:port. It is already in use by another process.
Reason:
The server tried to start using the ip and port values shown which were from the zowe configuration. When trying to connect to this address, the server recieved an error telling it that the address was already in use.
Action:
Check the system's network port status to see what program could be using this address, and either stop that program or change the zowe configuration to use a different address before restarting zowe.
ZWED0005E​
Could not listen on address ip:port. Invalid IP for this system.
Reason:
When the app-server was binding to the address shown, it recieved the error EADDRNOTAVAIL or ENOTFOUND. In either case, the app-server was not able to bind to the address and so it will not run until the problem is solved.
Action:
Review the address and check if it is valid or if there is some lack of permissions that might explain why these errors were received by the server.
ZWED0006E​
Usage: --inputApp | -i INPUTAPP --pluginsDir | -p PLUGINSDIR --zluxConfig | -c ZLUXCONFIGPATH [--verbose | -v]
Reason:

Action:
Retry the operation after modifying the input arguments to be valid against the list shown. Or, if you are trying to do app installation, you should use zwe components install instead whenever possible.
ZWED0007E​
serviceName invalid version version
Reason:
The service mentioned was trying to be loaded by the server but failed validation due to the version number not being a a valid semver string. This service and therefore plugin will be skipped during loading.
Action:
Contact the developers so that they can revise the pluginDefinition.json of the plugin where the service is located to be semver-compatible. Details on semver version can be found at semver.org
ZWED0008E​
localServiceName: invalid version range serviceName: versionRange
Reason:
When the serviceName was trying to be imported into a plugin as localServiceName, the version range of acceptable versions for the service to be imported was not valid. Due to this, the import cannot be resolved and the plugin will be skipped in loading.
Action:
Contact the developers of the plugin this error occurred in as the pluginDefinition.json needs to be revised to have the version range given for this import service be a valid semver range string.
ZWED0009E​
localServiceName: invalid version range versionRange
Reason:
When the a service was trying to be imported into a plugin as localServiceName, the version range of acceptable versions for the service to be imported was not valid. Due to this, the import cannot be resolved and the plugin will be skipped in loading.
Action:
Contact the developers of the plugin this error occurred in as the pluginDefinition.json needs to be revised to have the version range given for this import service be a valid semver range string.
ZWED0010E​
No file name for data service
Reason:
When the server was trying to load a service for a plugn, it couldn't identify the filename where the service is located within the plugin, so the service and therefore plugin have been skipped during loading.
Action:
Contact the plugin developer to fix that the service within the pluginDefinition.json is missing the "fileName" or "filename" property which must describe the path to the dataservice entry file, relative to the plugin's lib directory.
ZWED0011E​
Plugin pluginId has web content but no web directory under location
Reason:
The plugin definition of pluginId stated that the plugin has web content to serve such as HTML files, but the required 'web' folder was missing, so the plugin cannot be loaded.
Action:
Check that the web folder within this plugin exists or not. If it does exist, then the server may not have had permission to read it. Otherwise, if it doesn't exist, try to reinstall the plugin in case it is corrupt. Or, contact the developers to fix the lack of web directory.
ZWED0012E​
pluginId::serviceName Required local service missing: localService
Reason:
The service serviceName could not be loaded because of an unsatisfied version requirement upon another service. This causes the plugin pluginId to be skipped during loading.
Action:
Review the plugin's definition to see why the version match could not be made. Either a required plugin is missing, or the pluginDefinition.json will need to be revised by the developer of the plugin to fix the version check failure.
ZWED0013E​
pluginId::serviceName Could not find a version to satisfy local dependency serviceName@requiredVersion
Reason:
The service serviceName could not be loaded because of an unsatisfied version requirement upon another service. This causes the plugin pluginId to be skipped during loading.
Action:
Review the plugin's definition to see why the version match could not be made. Either a required plugin is missing, or the pluginDefinition.json will need to be revised by the developer of the plugin to fix the version check failure.
ZWED0014E​
Plugin pluginId invalid
Reason:
The plugin could not be loaded because the plugin definition was not valid in some way. There are fields that every plugin must define, such as type. Then, depending on type, there are more fields a plugin can and cannot have. When the server went to load the plugin, it found that the definition was not correct versus the requirements, so the loading of this plugin was skipped.
Action:
Contact the developers of this plugin so that they can fix the plugin to adhere to the plugin schema
ZWED0015E​
No plugin directory found at pluginLocation
Reason:
The server finds plugins by reading JSON files within the "plugins" folder of its workspace directory. When it checked the JSON of this particular plugin, the JSON stated the plugin could be found at a folder pluginLocation which either does not exist or could not be read by the server.
Action:
Check that the location shown exists. If it does exist, then there is some permission problem preventing the server from reading it. If it does not exist, determine whether this plugin is desired but has the wrong location, or if this plugin is not desired and should be removed. Contact support so they can assist in fixing the plugin location problem.
ZWED0016E​
No pluginDefinition.json found at pluginLocation
Reason:
The server finds plugins by reading JSON files within the "plugins" folder of its workspace directory. When it checked the JSON of this particular plugin, it stated the plugin was located in a folder which the server determined did not contain the pluginDefinition.json file that every plugin requires. Due to this missing file, the loading of this plugin was skipped.
Action:
Check that a pluginDefinition.json exists at the location specified. If it does, then the server is missing permissions necessary to read the file. If the file does not exist, review if there is a problem with the plugin itself that should be resolved by contacting the plugin developers. If the plugin exists with a pluginDefinition.json file at a different location than the error suggests, contact Zowe support to resolve the location problem.
ZWED0017E​
Identifier doesn't match one found in pluginDefinition: pluginIdentifier
Reason:
The identifier found in the plugin reference doesn't match the one specified in the pluginDefinition.json
Action:
Check if identifier found is the same one as intended (typo perhaps?). If not, delete the plugin identifier JSON (found in instance/workspace/app-server/plugins) and restart Zowe. If issue isn't resolved, increase app server debugging and send logs to the app developer
ZWED0018E​

The server was trying to determine a network port to use for a Java dataservice, but no available ports could be found, so the server cannot load that service.
Action:
Check your Zowe configuration to see if you have enough or any ports specified for the app-server to use when assigning ports to Java dataservices.
ZWED0042E​
Could not find runtime to satisfy group: javaRuntime
Reason:
When trying to run a group of Java dataservices under a common java runtime, the javaRuntime couldn't be found, so the dataservices cannot be run.
Action:
Check the configuration for this group of Java services to see if javaRuntime is a good value, and resolve the Java issue before restarting the server.
ZWED0043E​
Unknown java app server type=javaRuntimeTime specified in config. Cannot continue with java loading.
Reason:
The app-server can only handle Java dataservices if they run under certain types of Java server runtimes. The type chosen was not one of the types supported, so the server cannot continue with the loading.
Action:
Check if the version of the plugin you are using is compatible with the version of Zowe you are using. Check if you can change the "type" of java server to one that the app-server does work with, such as "tomcat".
ZWED0044E​
Java runtimes not specified, and no JAVA_HOME set
Reason:
The app-server cannot run the java dataservices because it doesn't know how to start any Java with the configuration specified.
Action:
Either define the environment variable JAVA_HOME to point to a valid Java runtime home, or specify a Java runtime within the app-server configuration as components.app-server.languages.java.runtimes. For more information, see the server schema https://github.com/zowe/zlux-app-server/blob/v2.x/master/schemas/app-server-config.json
ZWED0045E​
Java app server not defined in config
Reason:
A dataservice was configured to run from a WAR file but the configuration section components.app-server.languages.java.war.javaAppServer was missing, so the app-server could not run the dataservice.
Action:
Define the missing configuration section according to the app-server schema https://github.com/zowe/zlux-app-server/blob/v2.x/master/schemas/app-server-config.json or remove it and the plugin that required it.
ZWED0046E​
JavaManager not given either war or jar configuration options, nothing to do
Reason:
A java dataservice was requested but the components.app-server.languages.java configuration section of Zowe was missing either a war or jar subsection. Since one of the two is needed, the server could not continue with loading the java dataservices.
Action:
Review the app-server schema https://github.com/zowe/zlux-app-server/blob/v2.x/master/schemas/app-server-config.json and your Zowe configuration file to identify and correct the missing properties within components.app-server.
ZWED0047E​
Proxy (pluginid:servicename) setup failed. Host & Port for proxy destination are required but were missing. For information on how to configure a proxy service, see the Zowe wiki on dataservices (https://github.com/zowe/zlux/wiki/ZLUX-Dataservices)
Reason:
A proxy was requested by the service pluginid:servicename but the service configuration or pluginDefinition did not specify what the proxy destination was, so the server is skipping the loading of that plugin.
Action:
Review the plugin's configuration or contact the developer of that plugin to correct the proxy configuration.
ZWED0049E​
Can't specify error metadata
Reason:
When a dataservice called the utility function makeErrorObject, it did not supply context of the _objectType and _metaDataVersion, which are required and caused the function to throw its own error about the lack of information.
Action:
Contact the developer of the plugin which caused this error.
ZWED0050E​
Root service serviceName not found
Reason:
A dataservice tried to call a "root", or non-plugin service of the app-server or app-server's agent, and this root service serviceName was not found on the server, so the request failed.
Action:
Verify that your version of Zowe works with the plugins that you have installed, and contact the developer of the plugin which tried to call this missing root service.
ZWED0051E​
Could not resolve service URL. Plugin=pluginId, service=serviceName
Reason:
A dataservice serviceName handled by a language manager could not be used because the URL in which to access this dataservice from its language manager could not be determined.
Action:
Check the logs to see if there was trouble installing the service or plugin, and contact the developers of pluginId for more support.
ZWED0052E​
Could not load service pluginId:serviceName due to unknown type=serviceType
Reason:
The service from the plugin shown could not be loaded because the plugin declared the service to be of some type that the app-server does not handle.
Action:
Check to see if the version of Zowe you are using works with the version of the plugin you are using. Plugins must have dataservices only of types seen within the pluginDefinition schema https://github.com/zowe/zlux-app-server/blob/v2.x/staging/schemas/plugindefinition-schema.json
ZWED0053E​
Import sourcePluginId:sourceServiceName can't be satisfied
Reason:
A plugin trying to load a dataservice from sourcePluginId:sourceServiceName couldn't load that service, therefore the requesting plugin will fail to load.
Action:
Confirm that the source plugin and service exist. Check the logs to see if there was something that caused the source service to fail loading. Contact the developers of either source or target plugin for more assistance if the cause is not clear.
ZWED0111E​
SEVERE: Exception occurred trying to generate object from input: error
Reason:
The server could not parse its input configuration due to the error shown, so the server cannot start.
Action:
Review the error to determine the cause, or contact support if the cause is unclear.
ZWED0112E​
The server found no plugin implementing the specified default authentication type of type.
Reason:
The value of components.app-server.dataserviceAuthentication.defaultAuthentication within the server configuration specified a type of authentication that some authentication plugin must implement in order for the server to run. Because no plugin that successfully loaded declared that it implemented this type, the server found no implementation and could not continue.
Action:
Review if any plugin you have implements the given type. If the type is incorrect, revise the configuration to choose a type that does exist in your system. If the type is correct, check if you are missing a required plugin.
ZWED0113E​
The server found no authentication types. Verify that the server configuration file defines server authentication.
Reason:
The server was unable to find any authentication plugins where at least one is required to run.
Action:
Review the list of plugins that are being used and see if any authentication plugins you needed have failed to load, and review their error messages.
ZWED0114E​
The server found no plugin implementing the specified default authentication type of type.
Reason:
The value of components.app-server.dataserviceAuthentication.defaultAuthentication within the server configuration specified a type of authentication that some authentication plugin must implement in order for the server to run. Because no plugin that successfully loaded declared that it implemented this type, the server found no implementation and could not continue.
Action:
Review if any plugin you have implements the given type. If the type is incorrect, revise the configuration to choose a type that does exist in your system. If the type is correct, check if you are missing a required plugin.
ZWED0115E​
Unable to retrieve storage object from cluster. This is probably due to a timeout. You may change the default of 'storageTimeout' ms by setting 'node.cluster.storageTimeout' within the config.
Reason:
The app-server was running in cluster mode and a service attempted to get content from the cluster storage but this failed. Because storage could not be read, its possible the service that requested the storage will have further errors.
Action:
If there was a network disruption or performance issue, a timeout could have occurred. Review the rest of the logs to see if there are other messages to explain the failure. You can attempt to avoid timeout-related failures by editing the configuration parameter components.app-server.node.cluster.storageTimeout.
ZWED0145E​
Cannot load SAF keyring content outside of z/OS
Reason:
The Zowe configuration of zowe.certificate or components.app-server.node.https specifies SAF keyrings as locations to find keystore and truststore data. SAF keyrings only exist on z/OS, and the server detected it was not running on z/OS so it cannot continue.
Action:
Modify the configuration to use a different keystore type, or migrate the server to z/OS.
ZWED0146E​
SAF keyring data had no attribute "attribute". Attributes=attributeKeys
Reason:
Within the list of attributeKeys, attribute could not be found.
Action:
Check the keystore configuration of the server such as in zowe.certificate or components.app-server.node.https to see if it is valid for Zowe. The SAF keyring Zowe was configured to use may be missing a key and certificate pair, or certificate authorities keychain. For more suggestions on configuring keyrings for Zowe, review the install guide
ZWED0147E​
SAF keyring data was not found for "keyName"
Reason:
The server tried to read the SAF keyring specified within the Zowe configuration, but ran into an error where the server received no data instead.
Action:
Review the logs to see if a reason for the error is shown. Verify that the Zowe configuration points to a valid keyring that the Zowe server user has permissions to read.
ZWED0148E​
Exception thrown when reading SAF keyring, e=error
Reason:
The SAF keyring which the app-server was configured to use could not be read due to an error. The server likely will not start or will be unable to do any network activity until this error is resolved.
Action:
Review the error message to determine the cause. Often, the error messages will originate from a system service where the documentation can be found here https://www.ibm.com/docs/en/zos/2.5.0?topic=library-return-reason-codes
ZWED0149E​
SAF keyring reference missing userId "user", keyringName "name", or label "label"
Reason:
The server configuration specified that the app-server should load keystore and truststore content from a SAF keyring, but the syntax in the configuration was incorrect, because user, name, or label were not usable by the server.
Action:
Check the zowe.certificate or components.app-server.node.https sections of Zowe configuration to see if there are entries that start with safkeyring:// and verify that they are in the format of safkeyring://USERNAME:RINGNAME&LABEL. Older versions of zowe will require that there be 4 slashes, such as safkeyring:////. The &LABEL suffix is only needed for specifying certificate authorities and should be omitted in other sections, for example it is only needed within zowe.certificate.pem.certificateAuthorities or components.app-server.node.https.certificateAuthorities. For more suggestions on configuring keyrings for Zowe, review the install guide
ZWED0150E​
Cannot load SAF keyring due to missing keyring_js library
Reason:
The Zowe configuration specified that the app-server should load keystore and truststore information from a SAF keyring, which requires the nodejs library keyring_js. This library is defined within the package.json of zlux-server-framework and ships with Zowe installs, but could not be loaded for some reason and therefore the server could not load keyrings and will either stop or have issues with network communication.
Action:
Use the command zwe support to verify if the Zowe install has all files expected, as this message indicates the keyring_js library is missing and reinstalling Zowe may be required.
ZWED0151E​
Env var variableName not found
Reason:
The server was loading plugins. It determines the location of each plugin via a plugin pointer file. The plugin referenced in the logs, it's location is dynamically determined by an environment variable variableName. Because the variable did not resolve to a value, the plugin could not be found and could not be loaded.
Action:
Review the documentation for the plugin that failed to load, check what the value of the variable should be, and contact support for that plugin if needed.
ZWED0152E​
Unable to locate server config instance location and INSTANCE_DIR environment variable does not exist.
Reason:
While installing a plugin, the server could not determine the location of the configuration dataservice's "instance" folder. Due to this, the plugin could not be completely installed.
Action:
Correct the error before reinstalling the plugin. This error could happen due to an incorrect value for components.app-server.instanceDir and normally defaults to {{ zowe.workspaceDirectory }}/app-server.
ZWED0153E​
(operatingSystemName) is not a supported platform for componentName. Skipping (pluginid)... Supported: requiredOperatingSystem
Reason:
The Zowe host operating system operatingSystemName is not supported by the component componentName. Supported platforms are defined in the component's pluginDefinition.json.
Action:
Refer to componentName pluginDefinition.json for supported platforms. The installation of Zowe may also be moved to a supported platform. Lastly, contact the author of the component, or a system administrator.
ZWED0154E​
(architectureName) is not a supported architecture for componentName. Skipping (pluginid)... Supported: requiredArchitecture
Reason:
The Zowe host architecture is not supported by componentName. Supported architectures are defined in the component's pluginDefintion.json.
Action:
Refer to componentName pluginDefinition.json for supported architectures. The installation of Zowe may also be moved to a supported architecture. Lastly, contact the author of the component, or a system administrator.
ZWED0155E​
(url) is not a supported endpoint for componentName. Skipping (pluginid)... Supported: urls
Reason:
The endpoint url does not match any required endpoints of componentName. Supported endpoints may be viewd in the component's pluginDefinition.json.
Action:
Refer to componentName pluginDefinition.json for supported endpoints. Optionally, remove url from the required endpoints in pluginDefinition.json. Lastly, contact the author of the component, or a system administrator.
ZWED0156E​
Could not register default plugins into app-server.
Reason:
org.zowe.zlux.json is missing from app-server plugin directory. This error will cause the process to exit.
Action:
Verify integrity of Zowe installation, or contact system administrator. Please refer to https://docs.zowe.org/stable/appendix/zwe_server_command_reference/zwe/support/zwe-support for collecting Zowe runtime information.
ZWED0157E​
Could not register default plugin pluginid into app-server.
Reason:
Could not register default plugin pluginid into app-server due to plugin upgrade failure.
Action:
Verify integrity of plugin files, or contact system administrator. Please refer to https://docs.zowe.org/stable/appendix/zwe_server_command_reference/zwe/support/zwe-support for collecting Zowe runtime information.
ZWED0158E​
Could not listen on address ipAddress:port. Insufficient permissions to perform port bind.
Reason:
Server could not bind to port due to an EACCES error. User lacks privilege to perform port bind. This error will cause the process to exit.
Action:
Contact system administrator.
