Error 404 when trying to generate images (Google/Imagen) - Upstream Not Found

[samuelnatan]

Hi everyone! I'm having some trouble trying to generate images using the local server (port 8045).

Generating text (like with gemini-2.5-flash) is working perfectly fine for me. But whenever I try to generate an image using models like gemini-3-pro-image or imagen-3.0-generate-001 via API request, it fails and I get a 502 Bad Gateway error in my script.

I opened the Debug Console in the Antigravity Tools app, and I noticed this error loop (I've attached a screenshot as well):

It looks like Google might have changed or blocked this internal endpoint for image generation. Is this feature currently broken for everyone, or is there a specific setting/proxy I need to change to make it work again?

Thanks for the help and for the great tool!
