When running Twenty on self-hosting instance, I found this error appear in the console

BullMQ: DEPRECATION WARNING! Your redis options maxRetriesPerRequest must be null. On the next versions having this settings will throw an exception

Could you try something like this and tell us if it goes away? (and raise a PR if it does). Thanks a lot!
