    public function actionIndex()
    {
        $model = About::getDefaultAbout();

        $this->setMetaParams($model);

It seems like $model can also be of type array; however, parameter $model of app\controllers\BaseController::setMetaParams() does only seem to accept null|yii\db\ActiveRecord, maybe add an additional type check?

        return $this->render('index', [
            'model' => $model
        ]);
    }
