Discourse AI error (Gemini 1.5)

Contribute Bug

AI-generated summary

A user reports an error in the Discourse AI plugin related to the Gemini 1.5 API, specifically an undefined method 'dig' for nil:NilClass error occurring in the extract_completion_from method Truest. The full backtrace points to a failure in processing an API response, likely due to a nil value being passed to the dig method. Falco asks for more details, and the user provides the full backtrace Truest. Another user, Falco, suggests checking the API key and server connectivity, which the original user confirms is not the issue Truest. The discussion is ultimately closed as stale by sam, noting that 2.5 flash and pro are well supported.

Gemini 1.5 is working fine for us here, are you sure your API key is working and that your server can reach the Gemini API ?

Yes, I’ve actually been using it without any issues.

If it works properly without having to do a separate Google OAuth authentication for the API key, I’m confident I’ve configured everything correctly.

Sorry closing this as stale, 2.5 flash and pro are very well supported these days.
