Stuck on syncing with SSS

[clokep]

Steps to reproduce

1. Opened the application
2. Saw the "Syncing..." icon
3. Nothing updated

---

I attempted to "clear cache" to see if that would fix it. After the app restarted my avatar was no longer there and it was still stuck in a syncing/broken state.

Eventually my avatar appeared, but nothing else?

Outcome

What did you expect?

The app to update with new messages

What happened instead?

The app was stuck on syncing.

Your phone model

iPhone 14

Operating system version

iOS 18 (although it was happening yesterday with 17.x)

Application version

1.81 (123)

Homeserver

matrix.org

Will you send logs?

Yes

I submitted logs both before and after clearing cache. Can do so again if it is helpful.

TypeError: '<=' not supported between instances of 'NoneType' and 'int'

which means stream was None.

..becase this is setting a None value.

Thanks for fixing this so quickly!

Thanks for fixing this so quickly!

It might be a little bit before we get this deployed on matrix.org. But I'm hoping to do that today. 🤞

This seems to still be happening to me. (From @wrjlewis pinging me this morning I'm assuming we were hoping that element-hq/synapse#17727 would be the full fix and that it was deployed.) I did another clear cache and submitted logs.

Looks like updating to v1.8.2 fixed this for me? Anyway, stuff is working again. 🎉
