When I tried to input more than one images and requested Gemini 3.0 pro, 3.1 flash image generation codes to generate images, it always shown "Error on AI execution "warning message. I don’t know what is the source of the issue. But it is frustrating as it did not happened so frequently now.
You can check the error_message field in the conversation system table. Generally speaking, Gemini does experience some instability, which is an issue on the Gemini server side.
Gemini 3.0 Pro has been retired by google.
3.1 flash image on the other hand should be ok.
