Meaning

Services deployed without --allow-unauthenticated demand an ID token. Either make it public (allUsers with roles/run.invoker), or send Authorization: Bearer $(gcloud auth print-identity-token). Service-to-service calls need the calling service account to hold run.invoker on the target. An organisation policy may block allUsers.

Common causes

  • No Authorization header on a private service
  • Caller lacks roles/run.invoker
  • Token audience (URL) wrong
  • Domain-restricted-sharing org policy blocks allUsers
  • Ingress set to internal only

⚡ Quick fix

  1. For testing: curl -H "Authorization: Bearer $(gcloud auth print-identity-token)" URL
  2. Grant roles/run.invoker to the caller's service account
  3. Public service: gcloud run services add-iam-policy-binding SERVICE --member=allUsers --role=roles/run.invoker

Detailed fix by platform

gcloud

  1. gcloud run services add-iam-policy-binding SERVICE --member="serviceAccount:caller@PROJECT.iam.gserviceaccount.com" --role=roles/run.invoker --region REGION

How to diagnose

  1. Auth — Token sent?
  2. Role — run.invoker granted?
  3. Policy — allUsers blocked?
