Hi,
you cannot assign nothing to transaction item which is of type data row, and the datarow is from datatable you can try like datatable.newRow.
Since the transaction item you are getting is from queue it should be of type queue item.
First delete that assign activity and drop again activity from Activity panel. Then assign Nothing to TransactionItem variable. Check it will work. Please let me know if you face any issue.

This is a workaround. I have already put another workaround in the initial post, but I still think this is a bug that should be addressed by the development team.
I am also facing the same issue. Sometimes removing “Nothing” and then again re-assigning “Nothing” works. But, “Nothing” should be automatically assigned to any Data Type without error.
