Can't connect to the Rasa server

stjo15 commented 5 years ago

I've input the code snippets according to instructions in README.

<!doctype html>
<html lang="en">
  <head>
    <script type="module" src="https://unpkg.com/@assister/rasa@latest/dist/rasa/rasa.esm.js"></script>
    <script nomodule src="https://unpkg.com/@assister/rasa@latest/dist/rasa/rasa.js"></script>
    <link href="https://unpkg.com/@assister/rasa@latest/dist/rasa/rasa.css" rel="stylesheet">
    <style>
      :root {
    /* --header-background-color: gray; */
    /* --header-text-color: black; */
}
    </style>
  </head>
  <body>
    <rasa-bot server="http://localhost:5005" />
  </body>
</html>

I also tried with the public ip and domain name like this (the Rasa and Client app are on the same server right now):

<rasa-bot server="http://my-public-ip:5005" />

But I get thisoutput in the developer tools console:

rasa-bot.entry.js:267 POST http://localhost:5005/conversations/a3cceec6-d092-4608-a472-4d246d2ceacf/predict net::ERR_CONNECTION_REFUSED

The rasa server is running, port 5005 is open and I added this to credentials.yml:

rest:
#  # you don't need to provide anything here - this channel doesn't
#  # require any credentials

What's wrong here? Why is there no connection?

Same issue here.. I can CURL -X POST in the command line just fine to my Rasa localserver:5005 socket. First I run this command: rasa run -m models --enable-api --log-file out.log Then I can do:

curl -X POST http://localhost:5005/webhooks/rest/webhook --data '{
"sender": "Kenz", "message": "Hi there!"}'

Response: [{"recipient_id":"Kenz","text":"Hey! What information can I help you with?"}]%

But then using the rasa UI package and opening in browser, I say "hi" and I hear crickets.. :)

Probable cause

Thanks! Great project!

Maybe a gap in my understanding. Here's what I'm doing though.

Start Rasa server: $ rasa run -m models --enable-api --log-file out.log

Create simple server (Python+Flask) to render assister/packages/rasa/index.html (call it myServer.py):

from flask import (
    Flask,
    render_template
)

# Create the application instance
app = Flask(__name__, template_folder=".")

# Create a URL route in our application for "/"
@app.route('/')
def home():
    """
    This function just responds to the browser ULR
    localhost:5000/

    :return:        the rendered template 'home.html'
    """
    return render_template('index.html')

# If we're running in stand alone mode, run the application
if __name__ == '__main__':
    app.run(debug=True)

Run myServer.py in ZShell.

$pythonmyServer.py``


 * Serving Flask app "myServer" (lazy loading)

Open in browser: http://127.0.0.1:5000/

I see Headline "rasa-bot demo" and "Hello Rasa!" in Body. That's it.

Maybe a port issue? What port number is the UI scanning? I tried controlling Rasa's port number (different combos), still.

$ rasa run -m models --enable-api --log-file out.log -p 5002

Thanks! Best regards, hassan

Further info:

I edited index.html line #14: <rasa-bot server="http://localhost:5005"/>

Started Rasa server in ZShell: $ rasa run -m models --enable-api --log-file out.log

Then open in Firefox/Safari http://localhost:5000/. I get the Assistant UI. Then I send a message, and nothing happens. Except when I refresh the URL, my Rasa server complains:


Exception occurred while handling uri: 'http://localhost:5005/conversations/d89855fb-ead6-4d32-a001-d257698c37fe/predict'

Trying to get to the bottom of it. Not sure what else to do..

I can curl from command-line and get a response:

ry good\", \"sender\": \"user\" }"

For sure Rasa server is working properly.

Thanks!
