Migrations error moving from awx 19.0.1 to 21.0.0

Hello,
Migrations seem to fail on this one, looks like the db changed. Is there a way to fix it?

(awx) bash-5.1$ awx-manage migrate
Operations to perform:
Apply all migrations: auth, conf, contenttypes, main, oauth2_provider, sessions, sites, social_django, sso, taggit
Running migrations:

The above exception was the direct cause of the following exception:
