HTTP 400 - Invalid project resource name projects/ - Cannot complete onboarding

Google Antigravity
1

Hi,

I’m experiencing the HTTP 400 “Invalid project resource name projects/” error on macOS (Apple M3 Pro) and cannot complete the onboarding process.

What I’ve tried:

  • Clean reinstall of Antigravity

  • Reset Onboarding and Reset Post-Onboarding Setup

  • Created a new GCP project

  • Enabled 2FA on my Google account

  • Enabled cloudaicompanion.googleapis.com API on the project

  • Set cloudcode.project in settings.json

Current situation:

  • During onboarding, when I select “Use a GCP project”, every project I try returns “This Google Cloud Project is not supported”

  • I recently changed my primary Google account from to a Gmail address

  • The error persists across all my existing GCP projects

Account info:

  • New Gmail address used for login

  • Previous account: (no longer accessible)

  • Antigravity version: latest (just reinstalled)

  • macOS: Apple Silicon M3 Pro

Any help appreciated. Thank you.
