Meaning

The message names the metric and limit. Slow down with exponential backoff, batch requests, cache results, or request a quota increase in IAM & Admin → Quotas. Some quotas are per user, others per project.

Common causes

  • Burst of requests above per-minute quota
  • Daily quota exhausted
  • Loop calling an API without backoff
  • Many workers sharing one project quota
  • Quota left at the low default

⚡ Quick fix

  1. Add exponential backoff with jitter
  2. Request a higher quota in the console
  3. Batch or cache API calls

Detailed fix by platform

gcloud

  1. gcloud alpha services quota list --service=SERVICE.googleapis.com --consumer=projects/PROJECT

How to diagnose

  1. Metric — Which limit?
  2. Rate — Per minute or per day?
  3. Backoff — Implemented?
