Проблема с Yandex Translate Api

Получил API ключ Яндекса чтобы использовать в Android приложении, вроде бы должен работать, получал через сервисный аккаунт Яндекса. Для перевода текста использую данный метод.

    private String translate(String text) {
    YTranslateApi api = new YTranslateApiImpl(API_TRANSLATE_KEY);

    if (Build.VERSION.SDK_INT >= 24) {
        Translation translate = api.translationApi().translate(text, Language.EN);
        return translate.text();
    }

        return "";
    }

api translate key это тот api что я получил. При вызове метода вылетает данное исключение на строке Translation translate = api.translationApi().translate(text, Language.EN);
