Hi,

We started using the shop floor module on V17 entreprise on-prem with some quality checks. 

We're hitting an error message when some quality checks are passing.

psycopg2.errors.UniqueViolation: duplicate key value violates unique 
constraint "mail_followers_mail_followers_res_partner_res_model_id_uniq"
DETAIL:  Key (res_model, res_id, partner_id)=(quality.check, 4705, 1736) already exists.

It would seem that Odoo is trying to add the current user as a follower to the quality check and fails since the user is already a follower of the same quality check.

It seems to happen sporadically.

Any idea what could be the cause and how to fix it?
