gRPC 3 INVALID_ARGUMENT vs 6 ALREADY_EXISTS
Both gRPC 3 (INVALID_ARGUMENT) and 6 (ALREADY_EXISTS) 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, 6 means that the entity that a client attempted to create already exists. For example, a file or directory that the RPC was supposed to create already exists.
