Changelog Entry

Description

Prevent the backend from responding http error 500 when session_id is not provided by the client

Fixed

Fix issue #4158, ensure session_id is optional on the backend side.

Additional Information

I think this bug has been introduced with the commit https://github.com/open-webui/open-webui/commit/d97a4d687ebc065ae4ec2a45b24c775e052ab38c#diff-c867e0c9c90c94b02a2de567f2210ca9e600180d8fa3d6b121c7eb54da39a4edR345
we can see that session_id is optional on the client-side (see here: https://github.com/open-webui/open-webui/blob/c869652ef4907dd123a140d9a08a0c239e690b08/src/lib/components/chat/Chat.svelte#L394)
but this session_id is mandatory on the server-side, thus provoking an http 500 error when session_id is not provided (see here: https://github.com/open-webui/open-webui/blob/c869652ef4907dd123a140d9a08a0c239e690b08/backend/main.py#L1180).

Of course, if the websocket connection is not closed, we don't get this error. Yet, I think it is important to be robust in such situation. Probably the websocket connection should be re-established as well ?

Dear @tjbck , any insight would be welcome!
