gRPC 7 PERMISSION_DENIED vs 12 UNIMPLEMENTED
Both gRPC 7 (PERMISSION_DENIED) and 12 (UNIMPLEMENTED) 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, 12 means that the operation is not implemented or is not supported/enabled in this service.
描述
The caller does not have permission to execute the specified operation. This is not for unauthenticated callers — use UNAUTHENTICATED instead.
何时出现
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.
如何修复
Verify the caller has the correct IAM role, API scope, or access policy. Check RBAC configuration on the server side.
描述
The operation is not implemented or is not supported/enabled in this service.
何时出现
The client called an RPC method that the server does not implement. This often happens when the client uses a newer proto definition than the server supports.
如何修复
Verify the server version supports the method you're calling. Update the server to implement the missing method, or use an alternative endpoint.
