Hello community,


Platform: Nintex Workflow for O365

Start a Task Assign - Parallel - Wait for First Response - is being Suspended





RequestorId: 9cc29440-a295-8b99-0000-000000000000. Details: Exception was thrown while executing workflow instance. Exception details: System.InvalidOperationException: The activity 'SingleTask_CreateListItemCancellationScope' with ID 6731 threw or propagated an exception while being canceled. --->


When the Task Assign run, there is 2 Task Assign. 

The Participants is to 2 individuals and NOT a group.



Once a User has responded, the other Task is usually removed.
However lately, the 2nd Parallel Task remains and/or the workflow is Suspended

Seems like the other Task Assign cannot be removed and is causing the exception.


Nintex Experts, please help

Hi Garrett,


I'm going to recommend getting in touch with support for this one to see if it can be replicated. 


@SimonMuntz, have you seen this before?
