Frontend Widget Not Receiving Bot Responses

Rasa Pro CALM

Hi Rasa Community,

I’m working on integrating a frontend widget with my Rasa bot using Socket.IO. While the connection between the frontend and Rasa seems to be working, I’m not receiving any responses from the bot. Here’s a breakdown of my setup and the issue:

What’s Working

  1. Rasa Server: Running with rasa run --enable-api --cors "*".
  2. Actions Server: Running with rasa run actions.
  3. Socket.IO Connection: The frontend widget successfully connects to the Rasa server (confirmed by connect event).
  4. Frontend Widget: Using Rasa chat widget:

What’s Not Working:

The bot is not responding to messages sent from the frontend widget. No bot_uttered events are received in the frontend.

Steps I’ve Taken:

  1. Configuration: Updated credentials.yml to enable Socket.IO :

socketio: user_message_evt: user_uttered bot_message_evt: bot_uttered session_persistence: true

Verified endpoints.yml points to the correct actions server:

action_endpoint: url: “http://localhost:5055/webhook”

  1. Frontend Code: Using the Rasa chat widget script:
  1. Testing: Tested the bot with rasa shell and confirmed it responds correctly. Checked Rasa logs for errors but found nothing unusual.

What I Need Help With:

Why is the bot not sending responses (bot_uttered) to the frontend widget? Are there any common pitfalls or misconfigurations I might have missed?

Here are my Rasa version and dependencies:

Rasa: 3.6.0 Python: 3.9 @rasahq/rasa-chat: Latest version

Any guidance or suggestions would be greatly appreciated!

Thanks in advance,

Add --debug and see if confirm that the Rasa sees the message from the user.
