gRPC 5 NOT_FOUND vs 12 UNIMPLEMENTED
Both gRPC 5 (NOT_FOUND) and 12 (UNIMPLEMENTED) belong to the gRPC Status Codes category. 5 indicates that some requested entity was not found. For example, a file or directory that the RPC was supposed to operate on does not exist. Meanwhile, 12 means that the operation is not implemented or is not supported/enabled in this service.
