@xmpp/connection disconnect - Cannot read properties of null (reading 'end')

[filipw01]

Describe the bug
Calling client?.disconnect it's possible that this.socket is undefined

Logs
I didn't get a chance to reproduce it locally. Only attaching sentry logs

I suspect it could be a case when client is already disconnected but please let me know if I should provide more logs/reproduction

Environment
Browser

I agree it should throw if socket is undefined.

Can you send a PR?
