Randomly occurring: The app encountered an error processing your request.

Error type: <class 'openai.BadRequestError'>
Happening in both Chat & Ask. I ask the same bunch of questions several times and randomly get this error on a previously asked question. Refreshing doesn't fix but appears to resolve itself after a period of time.

Logs don't show anything of note.

Anyone else seeing this behaviour?

Found the answer in Application Insights - Errors.

This model's maximum context length is 4096 tokens. However, your messages resulted in 14821 tokens. Please reduce the length of the messages.

I increased the chunking size and when you ask for multiple sources, the response is additive. Reduced to 1 source and issue resolved.

Interesting, we have logic that tries to truncate the old conversation to fit in the message history, so it should have just truncated to 4096. However, it will fail if even a single question's sources exceed the token window. I made a lil video showing that message truncation logic- https://youtu.be/GIuj_w2HlT0
Glad you figured out a workaround!
