> Also - question - I understand that this is purely celery thing ? When
celery uses the DB, they manage their own migrations? I looked in our
migrations and I have not found any celery migrations we run :)?
In our side, we run a query that somehow calls the new field and fails. It
was reported in our internal testing of main yesterday.
