Frontend Widget Not Receiving Bot Responses

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](http://localhost:5055/webhook)"

2. Frontend Code:
   Using the Rasa chat widget script:

3. 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.
