It seems like $lang defined by $request->getQuery('lang', 'en_US') on line 81 can also be of type array; however, Zend\I18n\Translator\Translator::setLocale() does only seem to accept string, maybe add an additional type check?

        // Inject current language in view model
        $e->getViewModel()->setVariable('lang', $lang);
    }
