Retrieving customData in core actions

I have set a react prop customData={{"userId": "123"}} according to the README page. I have successfully connected rasa-webchat to rasa_core via socketio. I cannot get that customData in my custom rasa_core actions.

Issue: Missing a hint in README on how to retrieve this customData in rasa_core. This may be very useful for many novices like me.

The general problem: Identification of the user in the rasa core actions. To achieve this I need either:

• Extract senderId from rasa-webchat component in react frontend and attach this id to the user in the database.
• Supply custom senderId or customData to rasa-webchat.

However, I cannot do any of these. I cannot access senderId in the react component. And I cannot set my custom senderId. The rasa-webchat react component is closed.

It doesn’t yet… I was suggesting a possible addition. But since you found your way there’s no need
