429 RESOURCE_EXHAUSTED on Google AI Ultra plan with zero usage — Bug AG-859

I’m on the Google AI Ultra plan and have never successfully used the AI agent — zero usage on this account. Every request immediately fails with 429 RESOURCE_EXHAUSTED. This has persisted for multiple days, not a temporary rate limit.

  • OAuth sign-in works fine, account correctly shows “Google AI Ultra”
  • The error occurs on the very first request after sign-in
  • All retry attempts (1->2->3) fail with the same 429
  • Switching models doesn’t help
  • In-app “Provide Feedback” also fails to submit (network
    timeout)

From ls-main.log:
planner_generator.go:318] Encountered retryable api error.
retrying in 5s.
Error: RESOURCE_EXHAUSTED (code 429): Resource has been exhausted (e.g. check quota).

agent executor error: model unreachable: RESOURCE_EXHAUSTED (code
429)

Antigravity version: 1.107.0, macOS (Apple Silicon)

This appears to be the backend quota provisioning issue tracked as Bug AG-859 — Ultra account has zero quota allocated despite successful authentication and correct plan display.
