I get that message. Not sure if caused by RM.

This isn't related to the RM. It appears an add-on has added a "created_by" field to the widget system but hasn't defined the field properly (with a default). Unfortunately, it's hard to guess what add-on may have done this, but you'd need to get guidance by the author (and they need to release a fix with the correct field definition).
