Subject: Critical API Error: HTTP 429 RESOURCE_EXHAUSTED / Cloud AI Companion Route Block

Hello Google Support Team,

I am encountering a persistent rate-limiting block while using the Google AI platform. My environment is throwing an immediate HTTP 429 error, indicating that resources have been exhausted, despite my usage remaining well within valid project quota boundaries.

The issue appears to be a backend routing or authentication desynchronization originating at the Edge Server Filter (ESF) layer.

Please see the specific trajectory data and trace logs below for your engineering team to investigate:

  • Trajectory ID: 9cb04606-f4a7-421c-9acb-67c49018…
  • TraceID: 0x9ffa7b132b61..
  • X-Cloudaicompanion-Trace-Id: 9ffa7b132b6178..
  • Server Gateway: ESF
  • Timestamp of Incident: Mon, 07 Sep 2026 06:25:01 GMT

Error Payload:

json

{
  "error": {
    "code": 429,
    "message": "Resource has been exhausted (e.g. check quota).",
    "status": "RESOURCE_EXHAUSTED"
  }
}

Use code with caution.

Public developer forums suggest this is a known issue regarding project token bucket synchronization. Could you please check the backend routing for this specific TraceID, verify my project’s quota status, and manually flush the token/rate-limit bucket for my account if it has become stuck?

Thank you for your assistance, and I look forward to your update.

Best regards,
Shiva
