undefined method `dig’ for nil:NilClass" Error with Discourse AI Plugin

I’m encountering the following error while using the Discourse AI plugin:

Error Message:

Job exception: undefined method `dig' for nil:NilClass

Location:

/var/www/discourse/plugins/discourse-ai/lib/completions/endpoints/gemini.rb:107:in extract_completion_from’`

Context:

This error seems to occur when the code attempts to use the dig method on a nil value, likely while processing an API response within the extract_completion_from method.

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.
