Troubleshooting issues with the auto_join_rooms Synapse configuration option, I haven't been able to get users to join rooms (/ or have them auto-created, which it should do by default).
Starting fresh to try again, I've noticed that it works the first time, but breaks as soon as you change the rooms in the auto_join_rooms config. The only workaround seems to be starting fresh, which isn't ideal.
autojoin_success.log
autojoin_fail.log
autojoin_fail_manual.log
Steps to reproduce
Starting on a fresh server with the following set:
auto_join_rooms:
- "#banana:example.com"
- "#apple:example.com"
- "#orange:example.com"Works as intended, new users created either manually through the Admin API (/ console), via Delegated Auth, or through registering all join the three rooms.
However, changing the auto_join_rooms config seems to break it from ever working again for newly registered users. I changed it too:
auto_join_rooms:
- "#kiwi:example.com"
- "#pineapple:example.com"
- "#lemon:example.com"But any new users, receive the following error when synapse tries to auto-join them:
synapse.handlers.register - 586 - ERROR - POST-347 - Failed to join new user to '#pineapple:example.com': SynapseError('404: Room alias #pineapple:example.com not found')
I have also tried manually creating a room and giving it the alias, but this then hits:
synapse.handlers.register - 586 - ERROR - POST-347 - Failed to join new user to '#kiwi:example.com': AssertionError()
