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

 ![Screenshot 2025-06-27 at 08.20.23](https://global.discourse-cdn.com/meta/original/4X/3/8/2/3823376649f99b412fea517362b101d46199d62d.png)

### **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](https://github.com/discourse/discourse/commits/70dbb95041286abbe39accbd679f1ff100f9946d))

Thanks for your help!
