Steps to reproduce

1. Install Nextcloud+talk behind Authentik
   2. Use authentik's user id # for nextcloud's UID * I no longer believe this has anything to do with it, it just happened to be at a function call that gets the user id so I thought maybe it has something to do with it
2. Chat with people

Expected behaviour

Old chats should load

Actual behaviour

One chat I have with one user only loads up around 1/50 times refreshing the page. It doesn't load on the mobile app either. The other conversations I'm having work fine. the only clue i have is the 500 server error and the nextcloud.log log is related to the UID being interpreted as int's(loop variable $i is int but this version of? php expects str for index into (this?)map) instead of strings but they're required to be strings, also is strange(to me! Probably not to the program) that the log shows "no app in context" instead of "spreed" . The messages clearly send since the "last message" (right under the other users username) does always show the last thing sent in that conversation, even though the conversation itself will never load.

In this conversation we had exchanged text messages, tested Video chat (Pre- signaling server but post installing and configuring coturn) that worked well, I uploaded a screenshot from my android phone using the talk app to the conversation, and was switching between my PC and my phone with the app frequently.

I have already (I think) fixed the issue locally, opening the file SystemMessage.php I modified the failing function, simply adding "". before the $i to ensure it's a string when looking up in the paramaters['users'][RIGHT_HERE] and the chat loads again.

Did you by chance had a call with a user that only has numbers as user id?

[centerionware]

We did manage a video call, that when ended says @username ended the call with {user1} (Duration 1:29) in this, both user id's should be only numbers as assigned by authentik in my setup

[nickvergessen]

I managed to create the problem in a test

Reverted back to original, applied your patch, confirming the chat is still loading. Thank you!
