Critical Bug: Persistent HTTP 400 "Invalid project resource name projects/" even after Gmail switch

Google Antigravity

That really is the solution to the problem. I had to change my email address back to the one I used months ago when I signed up for the subscription and first started using Antigravatiy. Changing the email address for the Google account causes this error. That’s extremely poor on Google’s part. Is Google really unable to match these changes across all related products? Not to mention communicating this properly.

Are you on Pro or Ultra? I’ve been getting the same blank project ID error since the 11th Feb. I signed up to Antigravity Ultra using my own email @me.com address, worked perfectly until 11th Feb. Now every attempt to connect ends up in an HTTP 400 Bad Request. I don’t have a gmail alias associated to the account and so this fix won’t kickstart the backend auth for me.

I meet the same issue. But I only have one email account and it’s my gmail acount. so the upper trick doesn’t work for me. In my situation, I use antigravity for the first time without create a gemini api key. After I create a gemini api key (during this process, it also created a cloud project), this issue is fixed

No this didn’t work for me unfortunately, lucky you

worked for me , really thanks

I deleted Gmail, and antigravity works now. > After deleting it, I was asked to reactivate the service via SMS verification. > “Your phone number has been verified too many times.”

Goodbye, my Gmail. AND GOOD JOB, GOOGLE.

53

Have you fixed the issue?

Unfortunately, no. Obviously, the problem is that I unlinked the email from which the account was created and the subscription was purchased, but now I don’t have access to it. The problem is quite massive, but the support does not want to help in any way…
