Changelog Entry

Description

fixes #4025
fixed crash happening with IPv6 and some IPv4 setups where the backend crashes
- backend/main.py returns 500 Internal Server Error, since data["session_id"] does not exist in the JSON payload
- the JSON of the api/chat/completed POST request made by the chatCompletedHandler in src/lib/components/chat/Chat.svelte does not contain a session_id field
- this is because $socket?.id yields undefined (with IPv6)
this seems to be caused by const _socket = io('${WEBUI_BASE_URL}', { in src/routes/+layout.svelte
- WEBUI_BASE_URL is empty because of its definition in src/lib/constants.ts
fix: if io is initialized with a default url according to its docs to window.location.host everything seems to work without errors again

Fixed
