Whenever I am trying to claim, start the user task I am getting this error.

I crosscheck with task id I am getting the taskid and I am passing correct id as it is.

Here is the tasksummary:

[TaskSummary{id=4, name='User Task', description='', status='Ready', actualOwner='null', createdBy='swapnil', createdOn=Wed Jul 05 00:13:24 IST 2017, processInstanceId=4, processId='user.task.process', containerId='rtlsContainer'}]
