Tasks Stuck In Process Despite Approve/Reject Actions, No Errors Logged in Process Automation(OPA)

We are encountering an intermittent issue in Oracle Process Automation where tasks remain stuck in the process even after users perform Approve or Reject actions.

Details:

• Users complete the action successfully, but the task does not move to the next step.
• No errors or warnings are recorded in the audit logs for these tasks.
• The issue happens randomly and without a clear pattern.
• Restarting the process instance or re-starting the flow resolves the issue temporarily.

Please let us know if there are any known causes or solutions to help resolve this problem.

Best Regards,
