gRPC 7 PERMISSION_DENIED vs 14 UNAVAILABLE
Both gRPC 7 (PERMISSION_DENIED) and 14 (UNAVAILABLE) belong to the gRPC Status Codes category. 7 indicates that the caller does not have permission to execute the specified operation. This is not for unauthenticated callers — use UNAUTHENTICATED instead. Meanwhile, 14 means that the service is currently unavailable. This is most likely a transient condition, which can be corrected by retrying with a backoff.
Beschreibung
The caller does not have permission to execute the specified operation. This is not for unauthenticated callers — use UNAUTHENTICATED instead.
Wann Sie es sehen
The authenticated user lacks the required role, scope, or policy to perform this action. Different from UNAUTHENTICATED (code 16), which means no credentials at all.
Wie man es behebt
Verify the caller has the correct IAM role, API scope, or access policy. Check RBAC configuration on the server side.

Wann Sie es sehen
The server is overloaded, shutting down, or a network partition occurred. This is the most common code to retry on, as it's explicitly transient.
Wie man es behebt
Retry with exponential backoff. If persistent, check the server health, load balancer configuration, and network connectivity between client and server.
