Here are a few suggestions to troubleshoot this issue:

1. Workflow Step: Check if the issue is with the specific workflow step where the asset is being renamed. Try to isolate the problem by creating a simple workflow with just the rename step and see if the er....

2. Asset: There might be something specific about the asset that’s causing the issue. Try renaming a different asset and see if you still encounter the error.

3. Code Review: Review the code of your workflow step. The error message indicates that there’s a NullPointerException at JobHandler.process(JobHandler.java:403). This suggests that there might be an object that’s not been properly initialized.

4. Apache Felix Console: Check in the Apache Felix console whether the process step component class is in active state or not. If you do not see the class listed then check the status of the OSGI bundle which contains this clas....

5. Adobe Experience League Community: If you’re still unable to resolve the issue, consider reaching out to the Adobe Experience League Community. They might be able to provide more specific guidance or share experiences from similar projects.
