Function addsubdomain running twice

[mazzucode]

When i run the below code, xmlapi-php is running twice.

    require_once('../xmlapi.php');

    $cpanelUser = 'user';
    $cpanelPass = 'password';

    $XmlApi = new xmlapi('127.0.0.1');
    $XmlApi->set_port(2083);
    $XmlApi->password_auth($cpanelUser, $cpanelPass);
    $XmlApi->set_debug(1);

    $result = $XmlApi->api2_query($cpanelUser, 'SubDomain', 'addsubdomain', [
        'domain'      => 'marcio',
        'rootdomain'  => 'evoimobdev.com.br',
        'dir'         => '/usersite/marcio/public_html'
    ]);

So i get this result:

Someone knows why xmlapi-php is running twice?
