This method seems to be duplicated in your project.

    {
        if (Yii::$app->urlManager instanceof UrlManager) {
            $route = Yii::$app->controller->route;
            $params = Yii::$app->request->get();
            array_unshift($params, '/' . $route);

            return $params;
        }

        return ['/' . $this->getModule()->id . '/language/select'];
    }
}
