Invite to a room that has been deleted by a server admin cannot be accepted nor rejected

[eras]

Steps to reproduce

1. Get invited to a room
2. Somehow arrange the room to be removed (probably by server admins)
3. Try to reject the invite

Outcome

What did you expect?

I expected the invite to get rejected and the invite to get removed from my Element.

What happened instead?

The invite sticks permanently until clearing caches. A dialog pops up indicating the endpoint had returned a HTTP error (lost the logs already so I don't have the specific HTTP code).

Trying any of the three options (accept, reject, reject & ignore) available has the same outcome.

This sounds like a Synapse bug, as this used to work.

Yeah this is an issue where Synapse doesn't send it down /sync coming back

I'm not sure this ever worked. You may be thinking of matrix-org/synapse#2181, but in that case it was a remote invite from a server that became unreachable. In this case, the invite is from a user on the local server, but the room has since been deleted, which means we cannot generate a "leave" event.

This is also reported for element-android at element-hq/element-android#4720.

I'll file a new bug for Synapse.

Workaround for this is to clear the client-side cache, by the way.

Mine finally went away after a couple of days. The issue had nothing to do with cache or cookies for me, because my browser is set to clear those every time it's closed.

I spoke too soon. The invitation went away, but the room still exists and exhibits the same issue when I try to join the conversation in it.

[richvdh]

@Elliria I think you have a different issue.

[Elliria]

Okay.
