No response from rasa using socket.io

Rasa Open Source

Hello, I just created a new project with rasa init and trained a model with the sample data. The only changes are in the credentials.yml:

socketio:
      user_message_evt: user_uttered
      bot_message_evt: bot_uttered
      session_persistence: true

rasa run --credentials credentials.yml --cors * output:

~/.local/lib/python3.6/site-packages/rasa/shared/utils/io.py:89: UserWarning: Could not load local model in 'tests'.
2020-10-13 11:14:34 INFO     root  - Rasa server is up and running.
~/.local/lib/python3.6/site-packages/rasa/shared/utils/io.py:89: UserWarning: No policy ensemble or domain set. Skipping action prediction and execution.

rasa run --credentials credentials.yml --cors * --debug output:

There is no response in my frontend:

this.socket.on('bot_uttered', (data) => {
     console.log(data);
});

Update: I changed the sequence of ‘connect’ event and ‘session_request’. Now I get responses, but only in --debug mode. Without debug it is still the same output.

Are you running the commands in the same folder? It looks like the domain.yml wasn’t found in the first example…

Also, does changing --cors * to --cors “*” change anything?

“Also, does changing --cors * to --cors “*” change anything?”

That helped, thank you. Maybe a hint here would be nice:

--cors [CORS [CORS ...]]
      Enable CORS for the passed origin. Use * to whitelist
      all origins. (default: None)

Good to hear you go it sorted! I think it has to do with how the shell handles strings vs. commands but I’m not 100% certain. (Also not sure it would work for every type of terminal.)

I’m having the exact same issue…and my command is the same as mentioned in the currently marked solution…

rasa run --cors “*” --debug

Javascript code:

socket = io("http://localhost:5005");

socket.on('connect', () => {
    socket.emit("session_request", {
        "session_id": sid
    })
});

socket.on('bot_uttered', (data) => {
    console.log(data);
});

Here’s the network log
