HTTP 400 "Invalid project resource name projects/" - Google AI Ultra subscriber

I’m a Google AI Ultra subscriber and both Antigravity IDE Agent and Gemini CLI are returning HTTP 400 “Invalid project
resource name projects/”.

Account: Google AI Ultra plan
OS: Windows 11 (WSL2)
Antigravity version: latest

What I’ve tried (nothing works):

  • Clean reinstall of Antigravity
  • gcloud auth login --force --update-adc
  • gcloud config set project
  • Setting GOOGLE_CLOUD_PROJECT environment variable
  • Adding gemini.projectId to Antigravity settings.json
  • Gemini CLI also fails with 400 “Request contains an invalid argument”

The API is completely broken for my account. Even Gemini CLI cannot make any API calls. Please fix the account-level
provisioning issue.
