What could be causing the error: 'System of record(s) associated with this task instance is not found'? Is there a way to check what went wrong? I checked the apex_tasks table, and the task still exists with the status 'Assigned'. The workflowid for this task also exists.
I initially tried using apex_workflow.terminate, but the task was not canceled and remained in the 'Assigned' status. As a result, the task with this error is stuck. How can I resolve this issue?
