@aryanshridhar Thanks for the bug report! We definitely don't handle certain stream events, so I expect this could be related to that.

What version of zulip-terminal are you running?

[aryanshridhar]

Oh Fine @neiljp , I have updated the issue with the same .

@aryanshridhar I've not tested your case against the latest development version of ZT in git, but it may be more stable - I know we added some checks for unsubscribed streams at least.

It is still possible that this bug exists in the git version however, and certainly won't currently update the list of streams subscribed to - we need to handle more stream events in any case. I was looking into this in the last week or so.

[aryanshridhar]

Yup , The error exists in the git version as well .

$ zulip-term -v
Zulip Terminal 0.5.2+git
