Description

Not sure why it has started doing it, but I am seeing {"errcode":"M_NOT_FOUND","error":"Unknown room"} errors when trying to do an incremental sync.

Version information

• Homeserver: 0.33.9

EDIT1:

It's very likely

EDIT2:

synapse=# SELECT type, state_key, event_id FROM current_state_events
synapse-#                 WHERE room_id = '!YztxsnzcdfOllJOvZA:jcg.re';
     type      |        state_key        |             event_id             
---------------+-------------------------+----------------------------------
 m.room.member | @Half-Shot:half-shot.uk | $1537608760248JGTdh:half-shot.uk

my current_state_events table is miserable though.

EDIT3: Fixed by logging out and in, and doing an initial sync. I suspect I wasn't actually in the room and there was no state for it, however the sync I was using figured I was in the room hence the confusion. Not sure what there is to fix here. Perhaps we should drop any rooms that have incorrect state in the incremental syncs.
