Fix for Antigravity HTTP 400 – "Invalid project resource name projects/"

Google Antigravity
1

If you’re getting this error when logging into Antigravity with Google:

Trajectory ID / HTTP 400 Bad Request
Invalid project resource name projects/

Do NOT delete your Gmail. The issue is usually that Google Cloud access is blocked because 2-factor authentication (2FA) is not enabled.

Steps to fix

  1. Enable 2-factor authentication in your Google account.

  2. Go to Google Cloud Console: https://console.cloud.google.com

  3. Create a new project if you don’t already have one.

  4. Log out of Antigravity.

  5. Log back in with your Google account.

After creating a project and enabling 2FA, Antigravity should work normally.

Deleting Gmail is unnecessary and may permanently delete your emails.
