Matterbridge Matrix Bridge not working since both updated

[v1-valux]

Hello Nextcloud-Community,

i got sort of the same Issue as described here. I believe it stopped working since I updated Nextcloud and my Matrix instancea few weeks ago.

As stated by OP of the thread linked above, the issue was gone after a while (no clou why).. I guess my Issue could be a different rootcause, because it is not Telegram, but Matrix..

But I have no clou on how to troubleshoot this.

Matrix has had a recent change in Room versions (And a new Beta for 'Spaces'), but also with room version 6 (same version as from before the update) the bridge doesn't work anymore.. (I have not downgraded Matrix-Synapse tho)

I'm using the latest version of Matrix-Synapse (1.42.0)

Im using following versions of Talk/MB: Talk 12.1.1 Talk Matterbridge 1.22.4 (1.22.3 e45bbe45) Custom servers are configured (TURN/STUN)

This is the Matterbridge log (as nextcloud.log doesn't contain that issue):

I found no related bug-report or anything in changelogs that could explain, why the "lastMessage" attribute is not set anymore..

Also I'm wondering if matrix or nextcloud is the cause..

Any help is much appreciated.

Have a nice evening o/

Did you update recently? The presence of lastMessage should be optional now.

[gary-kim]

Yeah,you are on the most recent version. It should be fine if lastMessage is not set. Let me take a look at that.
