Assistance Needed: Unmarshalling Error After Redeploying Kogito Workflow

[Rizqi]

Dear Kogito Community,

I am encountering an issue after redeploying a Kogito workflow, and I would appreciate any insights or assistance.

Context:

• I made a minor change to the code (specifically, adding a space in the README file) and redeployed the workflow.
• Upon resuming the existing case, I encountered an unmarshalling error. But if i submit new case, the new case run smoothly.

I'm using postgre to as workflow persistence mechanism and already check in db, the existing process intance id still exist

Error Details: Here is the error stack trace that I am seeing:

Any guidance or suggestions on how to resolve this issue would be greatly appreciated.

Thank you for your assistance.

Hi Mas Rizqi, I think this Unmarshalling error is usually because there is a line of code has an error in the task operation method, whether because of NullPointerException (NPE) or something else, I suggest adding a try-catch block to specifically catch the error. You can also see it the error in kogito management console.

The same issue with u.

I tried to keep the previous version and clone a new version. Not sure problems is, but sometimes I see this issue when the previous version of the process ends.
