Issue: Receiving the subject error against the "Update Multiple Items" action in a simple workflow, but no evident way to determine specific issue with the action.
Context: List A in Site A is initiated by a Boolean field change in state, and when initiated the workflow's "Update Multiple Items" action is set to filter Site B's List B with the item title ("Accomplishment") field which is the same in both lists, and then to update the List B item's "Description" field with List A item's "Description" value. I've also tried changing from a Value assignment to a List Lookup on current item, but the same subject error is produced.
The Nintex Workflow version is 220.127.116.11.
If anyone has ideas about what might be causing the issue, and/or how to capture more granular details about the error, I'd appreciate it!
