Ionic 3 Получение Ошибка: Нет поставщика для NavController

Я получаю сообщение об ошибке:

Неподготовлено (в обещании): Ошибка: нет провайдера для NavController!

Это работало ранее с ионным 2, но как только я обновился до ионного 3, я начал получать проблемы.

Любая помощь по этому поводу требуется, я также заметил, что как только я удалю импорт HttpClient из LoginServer.ts, он будет работать правильно, поэтому не уверен, есть ли проблема с Угловым 4 Http-модулем.

Вот код
