Модернизация возвращает ноль

Я хочу получить данные пользователя из API, но когда я помещаю текст в текстовое представление, он становится пустым.

Мой класс объектов

Я хочу отображать детали (например, имя, идентификатор, номерной знак и т. д.) в разных текстовых представлениях. Но он возвращает пустую строку, т.е. null.

Вот мой API в формате JSON

Кто-нибудь может мне помочь?
