Not able to allow insert on remote schema permission

[H01001000]

I currently have two hausra instances, hausra A is connected to the database and has a table called message, hausra B is connected to hausra A with remote schemas. When I tried to add type mutation_root insert_message_one:message, and save it. It give error that

Saving permission failed
validation for the given role-based schema failed because expected default value of input value: "update_columns"of input object "message_on_conflict" to be [] but received

what should I suppose to do?
