gRPC 3 INVALID_ARGUMENT vs 5 NOT_FOUND
Both gRPC 3 (INVALID_ARGUMENT) and 5 (NOT_FOUND) belong to the gRPC Status Codes category. 3 indicates that the client specified an invalid argument. This indicates arguments that are problematic regardless of the state of the system. Meanwhile, 5 means that some requested entity was not found. For example, a file or directory that the RPC was supposed to operate on does not exist.
