gRPC 2 UNKNOWN vs 12 UNIMPLEMENTED
Both gRPC 2 (UNKNOWN) and 12 (UNIMPLEMENTED) belong to the gRPC Status Codes category. 2 indicates that an unknown error occurred. This may be returned when a server raises an exception that doesn't map to any known gRPC status code. Meanwhile, 12 means that the operation is not implemented or is not supported/enabled in this service.
الوصف
An unknown error occurred. This may be returned when a server raises an exception that doesn't map to any known gRPC status code.
متى تراه
The server threw an unhandled exception or returned an error that gRPC couldn't classify into a more specific status code.
كيفية الإصلاح
Check the server logs for the underlying exception. Wrap server-side errors with explicit gRPC status codes instead of letting them bubble up as UNKNOWN.
الوصف
The operation is not implemented or is not supported/enabled in this service.
متى تراه
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.
كيفية الإصلاح
Verify the server version supports the method you're calling. Update the server to implement the missing method, or use an alternative endpoint.
