Hi everyone,

I’ve encountered an issue while using the Discourse AI plugin with Gemini integration. When I try to analyze posts that contain images, I get the following error message:

no implicit conversion of Array into String

What happens

  • If the post only contains text, everything works as expected.
  • If the post includes an image , the analysis fails with this error.

Environment

Installed 3.5.0.beta8-dev (70dbb95041)

Thanks for your help!
