I’m using:

- rasa-core==0.12.0
- rasa-nlu==0.13.7

When running `train_online.py`, I have an error after saying hi to the chatbot `« ERROR:rasa_core.server:Can not access action 'None', as that name is not a registered action for this domain. Available actions are: … »`:

I don’t have any `None` actions. Is it linked to the fact that I have `day: None, duration: None, hour_start: None, name_room: None` after asking hi ?

Do you have any ideas ?
