Returncodes missing

Hi,
for CRUD I need the returncode 201 (created).

In RESTServer.inc every unknown code generates an watchdog_expression, even it is known in hook_rest_server_execute_errors_alter()
I need something like this:

diff --git a/sites/all/modules/contrib/services/servers/rest_server/includes/RESTServer.inc b/sites/all/modules/contrib/services/servers/rest_server/includes/RESTServer.inc
index 1f72ce8..4c3e227 100644
--- a/sites/all/modules/contrib/services/servers/rest_server/includes/RESTServer.inc
+++ b/sites/all/modules/contrib/services/servers/rest_server/includes/RESTServer.inc

       case 200:

+      case 201:
+         $error_header_status_message = $this->formatHttpHeaderStatusMessage('201', $error_message);

       default:

           $error_header_status_message = $this->formatHttpHeaderStatusMessage($error_code, $error_message);

Thanks
