$api->get method returns NULL

Hello,
I tried to use the module using api call.
I tried to get node by its nid:

   try {
     $api = services_client_connection_get('resources');
     $node = $api->get('node', 1);
     //var_dump($api->getDebug());
     var_dump($node);
   }
   catch (ServicesClientConnectionResponseException $e) {
     $e->log();
   }

but it always return NULL

using debug method I looked into retuned object and the field data was set to NULL value, but the raw_response was filled properly,
is this kind of bug, or am I missing something, which needs to be done? Setting response to JSON and updating your code to this prototype:

  public function get($resource, $id = NULL, $data = array()) {
    $this->http_request = $this->createRequest(array(
      'resource' => $resource,
      'id' => $id,
      'data' => $data,
      'action' => 'retrieve'
    ));
    $processed_request = $this->processRequest();
    if (!$processed_request->data) {
      $processed_request->data = json_decode($processed_request->raw_response);
    }
    return $processed_request->data;
}

helped me to load the data, but this is probably not the best solution. Should the data field always have any value?
