Antigravity HTTP 400: Invalid project resource name projects/

Google Antigravity
1

Antigravity fails on every request with HTTP 400.

Error:
Invalid project resource name projects/

Reproduced in:

  • empty workspace
  • new chat
  • after full reinstall
  • after clearing all caches
  • after reboot

Environment:
macOS (MacBook Air)
Latest Antigravity version

Trajectory ID:
f39ea4c7-2cdd-42e4-845a-

TraceID:
0x4f6c86ab

Looks like Antigravity is sending requests with an empty project resource:
projects/

Possibly a provisioning or account project binding issue.
