Hi @jian_bao
Welcome to the Google AI Forum!!!

Thank you for bringing this to our attention.
Could you please specify which model and version you are using when encountering this error?

I encountered the same error as him, at the same time, I used Gemini without any issues.

And I tried to change different models, but all displayed the same info.

My Antigravity Version: 1.20.5

Thank you!!!

Hey there it looks like I’m having the same issue however my situation is a little bit different. I had to migrate my Google workspace account to a brand new one due to a company name change and domain change. When this happened I started receiving this error using the same account that I have been using for a while in anti gravity.
