Как я могу решить проблему с данными, не отображаемыми из firebase-firestore в моем обзоре переработчика?

Question

Пожалуйста, мне нужна помощь по вопросу отображения данных из Firebase Firestore на моем RecyclerView

. Я создаю приложение, которое должно отображать список пользователей с указанием их имени, изображения, статуса и последнего чата. на RecyclerView. Я написал адаптер и все необходимые классы POJO, и он прекрасно работает, когда заполняет его вручную из кода

Однако я продолжаю сталкиваться с трудностями при попытке сделать это автоматически из пожарного магазина Firebase

См. мои коды ниже и структура базы огня ниже
