Success-страница после оформления заказа

Сделал по данному мануалу:
1. добавил параметр в системные minishop2


2. создал файл customorder.class.php в /core/components/minishop2/custom/order/ и зарегистрировал по документации через console


3. Прописал в настройках


4. Проверял как указано делая опечатку, ошибка 500 есть, класс подключен. Вот код файла нового обработчика:

}

Но редиректа не происходит… Так же обновляется страница с ?msorder=ID заказа
MODX Revolution 2.8.4-pl
Minishop2 4.1.4-pl

Может кто подсказать в чем ошибка?

if ($this->config['json_response']) {}

//Например этот участок кода

if ($this->config['json_response']) {
    /** Вот мои изменения ниже */
    $success_page = $this->modx->getOption('ms2_order_success_page');
    $this->modx->log(1, print_r($success_page,1))
    if(is_numeric($success_page)) {
        if ($this->modx->getCount('modResource', array('id'=>$success_page,'published' => true,'deleted' => false))) {
            $this->modx->log(1, print_r('1-1',1))
            $url = $this->modx->context->makeUrl($success_page);
            return $this->success('', array('redirect' => $url.'?msorder='.$order->get('id')));
	}
    }
    $this->modx->log(1, print_r('1-2',1))
    return $this->success('', ['msorder' => $msOrder->get('id')]);
}
$this->modx->log(1, print_r('2-1',1))
