I was wondering if it is planned to allow
action_session_start to work with a rasa action server. The docs for rasa action server (Introduction to Rasa Action Servers) state:
A Rasa action server runs custom actions for a Rasa Open Source conversational assistant.
Looking at https://github.com/RasaHQ/rasa/blob/b7d7f7014144715d8b03b60d96676003b66dee99/rasa/core/actions/action.py#L71 there is no reference to the action_endpoint for the
ActionSessionStart class, so it looks like this is currently not possible. Is there a practical reason for this, or has it just not been implemented? Would a PR to support this feature be welcome?
