Alright, I also figured something out: You can add the following line to the docker-compose.yml, next to the other livekit variables: FLUXER_LIVEKIT_DEFAULT_REGION: '{"id":"default","name":"Default","emoji":"🌍","latitude":0,"longitude":0}' The app can deal with a default region, this essentially just configures a default region and it'll work.
