Action error - "Delete row" -> this item

I don’t know about this problem.
“Delete Row” in action is actually good working,
but it put out some error message.
How can i didn’t get error message for this action?

I want to move updated row to another table, so I added row to another table and delete row on this table.

Not related to why the error is appearing, but why do you need to do this though? You’re changing some values in the current row, basically duplicate that to another table and delete the current row?
