Problem Description

In Antigravity (v4.1.29, macOS universal on M5 chip), the Agent execution always terminates with this error:

Error: HTTP 400 Bad Request
Message: Invalid project resource name projects/
Status: INVALID_ARGUMENT

Environment

  • OS: macOS (Apple Silicon M5)
  • Antigravity Version: 4.1.29 (universal.dmg)
  • Subscription: LoggedIn / Google AI Pro (会员,已登录 liwanying0525@gmail.com)
  • Google Cloud Console: No projects visible (no auto-provisioned “antigravity-xxx” or similar)

What I’ve Tried

  • Re-login / Sign Out multiple times
  • Clear local cache (~Library/Application Support/Antigravity)
  • Reinstall app
  • Reset onboarding via Cmd+Shift+P
  • Checked Google account: Pure @gmail.com, no Workspace, removed associated QQ email (743893112@qq.com)
  • Manual project creation in console + env var GOOGLE_CLOUD_PROJECT – still requests to empty “projects/”

Additional Info

  • Agent works in simple chat but fails on execution/Agent mode.
  • This seems like server-side provisioning failure (account entitlement not linked to a Cloud project).
  • Please escalate internally – many similar reports in forum (e.g., Critical Bug thread).

Thanks for help! Looking forward to fix.
