gRPC 7 PERMISSION_DENIED vs 15 DATA_LOSS
Both gRPC 7 (PERMISSION_DENIED) and 15 (DATA_LOSS) belong to the gRPC Status Codes category. 7 indicates that the caller does not have permission to execute the specified operation. This is not for unauthenticated callers — use UNAUTHENTICATED instead. Meanwhile, 15 means that unrecoverable data loss or corruption has occurred.
