✨ | Content Access | role/gid mapping refresh when gid missing (related to configuration synchronisation of content_access.settings and grey listing of roles with config_split)
I am also running into this issue and am trying to use #8 to fix the warning dumps happening. We have many roles defined by a team of content managers and users are seeing these warnings all the time. I upgraded to 8.x-1.0-alpha4 that was supposed to have a fix and one warning stopped and another one started in the content_access_optimize_grants call because the fix was to return a null if not found. I think this patch works better because it tries to fix the missing ids and clean out old grants with no id, since I can't imagine those are useful. I am on Drupal 9.4 and slowly upgrading to hopefully 10.X in the end. Going to run this one for a while and see how it goes seems to be working so far in testing.
