When submitting the Resource Adapter job we get an NJS-0001 error. Why?

Clarity PPM On Premise Clarity PPM SaaS


We are trying to run the job "GD Resource Adaptor V1.0".
When we click on the submit button we are getting error below:

"NJS-0001: Unable to process request due to server configuration or other technical problems. Contact your site administrator."


Any Clarity PPM release


Clarity PPM believes there is another instance of the job/ back-end process running and only one instance can run simultaneously.


1. Cancel and Delete any process instance of the Resource Adapter as only a single instance can run.
    By looking to the log files you can find the process instance is looking at: (Look at log files on the Additional Information section - Process Instance Id: 5760022)
2. The above process ID should be deleted as it is the one Clarity believes is running.
3. If the process has been deleted or is not present and the issue still persists, restart the app and bg services
