Incomplete bridging breaks Dimension: QueryRoomsForUser failed

[madprogramer]

Background information

• Dendrite version or git SHA: v0.9.4 (Docker Image)
• Monolith or Polylith?: Monolith
• SQLite3 or Postgres?: Postgres
• Running in Docker?: yes
• Using matrix-docker-ansible-deploy

Description

• What is the problem: Chats are not updating, bridge invites cannot be joined.
• Who is affected: Clients on my server
• How is this bug manifesting: Clientside messages fail to send. Logs show frequent "QueryRoomsForUser failed" errors (see below for sample)
• When did this first appear: While bridging with https://github.com/mautrix/facebook , I noticed that room invites were taking a bit long (slowdown). I shut down my server, updated, played with config a few times but now can no longer connect to any chats. Incomplete bridge joins fail repeatedly.

Deleting jetstream/$G/streams/DendriteInputRoomEvent and restarting did the trick. I guess that finally stopped the failed bridging for good.
