gRPC 1 CANCELLED vs 6 ALREADY_EXISTS
Both gRPC 1 (CANCELLED) and 6 (ALREADY_EXISTS) belong to the gRPC Status Codes category. 1 indicates that the operation was cancelled, typically by the caller. 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.
