How to redirect conversations to human - rasa (socket, channel))

[Deprecated] Rasa X Community Edition
1

I’m using rasa. I have the following scenario:

-user open webpage with chat(bot),
-user writes with both:
example:
u: hello,
b: hello, how can I help you?
u. I need something....
b. ...
u. I want talk to human
b-> redirect to human assistant (slot)

I read about helpdesk assistant, financial assistant GitHub - RasaHQ/helpdesk-assistant I created story. I created websocket using Java + Spring boot ws://localhost:5006/socket. Still not receiving messages on 5006/socket.

@mmuserdev are you able to manually send a message to "ws://localhost:5006/socket" and get the behavior you want? If so is it possible that the message being forwarded from rasa is not of the correct format?

What is wrong?

Ah, I see. That’s because you can’t implement handoff directly in Rasa X – handoff has to happen on the front end and Rasa X is not configured for that. You’ll notice the message “If you were connected to me on chatroom I would have handed you off…”

You’ll need to configure the chatroom frontend as described in the repo and talk to it there to implement the handoff.

Hello there, how exactly did you fix this? I am searching for a solution for this topic as well :slight_smile: The chatroom-feature does not work anymore. It looks like too many dependencies are deprecated.
