Error description

• Tokens cannot be deleted due to no task id found.
  Delete/move token from flow line returns success but nothing is
  executed.
  
  Problem description: In some odd cases some process instances
  may contain active tokens sitting on an event but the task no
  longer exists.
  The token cannot be deleted due to 'Task id not found' error.
  
  Also when a token is sitting on a flow line, when attempting to
  move / delete the token via REST API, it will return 200
  success code. However, the token is not removed.
  
     This is the error message logged
