ContinueChat on viewer hangs at 100% CPU usage #1623

Closed kuon closed 2 weeks ago

Hello,

I noticed that one bot would hang indefinitely at 100% CPU usage sometimes.

I was able to pinpoint the last requests made to the bot before it crashed:

I realize it's little to go on, I'll have to try to reproduce it in a debug environment, but maybe you can find something knowing the code.

Apparently the chatbot user, @Ulrfis says it was caused by an "incomplete" chatnode integration.

Ulrfis commented 2 months ago

The API key was missing in the Chatnode setting (because of a change of the API key in the Chatnode back-end)

I honestly have no idea 🤔 I don't think it is linked to Typebot... Is it 100% reproducible? On any bot, or just one?

kuon commented 2 weeks ago

I wasn't able to reproduce this. I investigated and it became clear that it is not a typebot bug. It is more a ky bug or even lower level bug. So I am going to close this.
