При срабатывании action.py он должен попасть в базу данных и сохранить информацию. И при запуске этого у меня появляется следующая ошибка TypeError: Parser must be a string or character stream, not NoneType.

Я получил None tomorrow None 30 min. Для получения этой информации я использовал tracker.getslot: 

class ActionBookRoom(Action):
    def name(self):
        return 'action_room'

    def run(self, dispatcher, tracker, domain):
        print("inside run")
        name_room = tracker.get_slot('name_room')
        day = tracker.get_slot('day')
        hour_start = tracker.get_slot('hour_start')
        duration = tracker.get_slot('duration')

А на стороне сервера действий у меня появляется следующее сообщение об ошибке:
