Symptom
NetWorker REST API operations fail with HTTP 500 (Internal Server Error).
Accessing any REST API end point from a web browser (https://NW_SERVER_ADDRESS:9090/nwrestapi/v3/global) reports:
There are no errors or information logged in the /nsr/logs/restapi/restapi.log.
Orsak
The NetWorker server operating system (OS) is not officially supported by the NetWorker version used.
For example, this issue appeared after upgrading an existing NetWorker server from Red Hat 7.9 to Red Hat 9.5 while using NetWorker 19.9. NetWorker 19.9 does not officially support Red Hat 9.5. This issue can also be observed without any upgrades, if a new NetWorker server version is installed on an unsupported operating system.
Upplösning
Ensure that the NetWorker version and server operating system meet support requirements.
