Insert error on MS SQL

Now trying to understand wappler. I have successfully connected to a MSSQL database. I am having an insert error: Cannot insert explicit value for identity column in table ‘feedback’ when IDENTITY_INSERT is set to OFF.

I have set the primary key column to auto-increment. I am not trying to manually insert any value as I am aware that the DB should take care of values to the primary key column. Why then am I getting this error? Any advice would be appreciated.
