& quot; Запрос не выполнен: в разрешении на операцию для имени отказано & quot; в запросе vtiger webservice, через который я хочу перечислить одну из записей модуля

У меня проблема с веб-сервисом vtiger. Любое тело, пожалуйста, помогите мне разобраться с этим. Я получаю эту ошибку «Запрос не выполнен: в разрешении на выполнение операции для имени отказано» в запросе веб-службы vtiger, с помощью которого я хочу перечислить одну из записей модуля.

Мой код:

$response = $httpc->doGet($params);
$httpc->disconnect();
$jsonResponse = Zend_JSON::decode($response);
if($jsonResponse["success"]==false)
