“An internal error occurred” when adding AI feature to the app

Hi,

I’m currently building an app with AI feature.

Now, after adding the AI feature and wanted to refine the app, Gemini 3 Pro preview is unable to respond and i keep getting the error “An internal error occurred”. I already tried the basic troubleshooting, clear the cache, reset conversation, use another browser, use incognito mode, but still error occurred.

Then, i tried to remove the latest change which was the AI feature added, then Gemini 3 Pro Preview works again. And, i ask to add the feature again which was successfully added, but when i ask to refine the app or update the app, Gemini 3 Pro preview not able to respond again an error “An internal error occurred”.

Please help if anyone encounter this issue also.

Got the same error at around the same time. It’s probably because this is a preview model and not the final release. Looks like it’s working correctly now

I just got on about an hour ago and have been getting this error as well. I’ve also noticed the agent takes WAY longer to complete a simple task or doesn’t complete the task at all even though I’m using Gemini 3 Flash
