Changelog Entry

Fixed

Fixed an edge case which caused the Chat page load to fail.

Additional Information

In some specific cirumstances, when messages or chat history is malformed, the retrieved message object can be undefined.
When this happens, the current code just returns it as [message].

This then causes an error when executing line 121 from /src/routes/s/[id]/+page.svelte:

history.messages[messages.at(-1).id].done = true;

because this line is trying to access an attribute that might not be available.

I have not looked into why the message object can be undefined though. That would be worth looking into.
