It looks to me like you have built a job worker to service the Human Tasks in processes.

The issue there is that the Tasklist component is itself a job worker that services these tasks. So what is happening in that scenario is this:

  • A Human Task job becomes available.
  • Your job worker code activates the task.
  • Because your job worker has activated the task, the Tasklist has not activated it.
  • Your job worker asks Tasklist to claim the task.
  • Because Tasklist did not activate this job, it knows nothing about it.

Your job worker has claimed the task. That is what activating the job is.

HTH,
Josh
