Platform 'Overseerr' not matched by plugin platform requirements

I’m getting this (insanely unhelpful) error message when trying to complete the onboarding flow for overseerr. Did the plex devs just brick something in a hotfix?
This was working literally three days ago (meaning I have not received a plex media server update or overseerr update since it was last working)
but after a server restart it’s just bricked. Overseerr is able to grab the list of registered media servers, but when it comes time to actually connect, it just fails out.

Plex has literally nothing to do with Overseerr… You’re better of reaching out to the Overseerr devs via their Discord for help.
