gRPC 7 PERMISSION_DENIED vs 13 INTERNAL
Both gRPC 7 (PERMISSION_DENIED) and 13 (INTERNAL) 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, 13 means that an internal error occurred. This means that some invariant expected by the underlying system has been broken.
Descripción
The caller does not have permission to execute the specified operation. This is not for unauthenticated callers — use UNAUTHENTICATED instead.
Cuándo lo verás
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.
Cómo solucionarlo
Verify the caller has the correct IAM role, API scope, or access policy. Check RBAC configuration on the server side.
Descripción
An internal error occurred. This means that some invariant expected by the underlying system has been broken.
Cuándo lo verás
A server-side bug, a corrupted internal state, or an unexpected failure in a dependency. This is the gRPC equivalent of HTTP 500.
Cómo solucionarlo
Check the server error logs and traces for the root cause. This typically indicates a bug that needs to be fixed in the server code.
