При ответе с сервера не полностью передаются значения полей в переменные

Хочу записать значения полей в переменные объекта класса Headers( соответствующее значение соответствующему полю). При получении респонса только некоторые поля корректно обрабатываются, остальные null. Почему так и как исправить? Не могу разобраться проблема в коде или конфликт зависимостей или черт знает что. package TestAPI;
