Assignment error

Unknown

Its difficult to see what the root cause of this issue is. The Set Assignments for Accounts requires that the assignment ID exist, it doesnt look like there is a check to see if there is anything valid coming out of the Get Current Assignment By Task Folder Id. It could be returning null, or it could be returning multiple assignments in any order.

If you know the specific Assignment you want to re-assign to a specific user, I would recommend using a fetch entities step to grab the Assignments and check the box to show output for only a single returned value. This will allow you to scope down and make sure you are getting the correct assignment that you are expecting.

Hope this helps.
