On initiating a mutation for an "edit item" action, based on the id(primary key) of the item in question, if the primary key provided is "null", all the rows in the table are affected. The desired behavior would be to return an error since the primary key is non-nullable.

Here is a screenshot of the issue:

As you see, all 5 rows have been affected.
