gRPC 5 NOT_FOUND vs 6 ALREADY_EXISTS
Both gRPC 5 (NOT_FOUND) and 6 (ALREADY_EXISTS) 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, 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.
