"tracker.get_slot" output None

Hi @Juste ! We have a similar problem with our bot. I post the error here : Slot - #3 by NathalieFouet

And when I try online.py, the error is :

? The bot wants to run ‘utter_greet’, correct? Yes ERROR:rasa_core.server:Can not access action ‘None’, as that name is not a registered action for this domain. Available actions are: - action_listen - action_restart - action_default_fallback - action_deactivate_form - utter_greet - utter_goodbye - utter_ask_room - utter_ask_day - utter_ask_hour_start - utter_ask_duration - action_room

Thanks :smile:
