Использование компонента архитектуры навигации с ящиком навигации

Я пытаюсь использовать Компонент архитектуры навигации (NavHostFragment) с Панель навигации (widget.NavigationView). Я получаю одну из следующих двух ошибок.

1) Это может произойти при выборе предмета из ящика несколько раз:

java.lang.IllegalArgumentException: navigation destination app.myDomain.navdrawertrials:id/action_rootFragment_to_settingsFragment is unknown to this NavController

2) Это происходит из моей реальной базы кода, которая настроена так же, как и в упрощенном примере ниже AFAICT. Почему бы не установить текущий узел навигации?

java.lang.IllegalStateException: no current navigation node
