Stuck in "Waiting for server..."

[jeanpah]

Hi, i need some help please

Im trying to use the plugin with socket.io in localhost but the chat plugin gets stuck at "Waiting for server..." phase.
This is the code fragment i'm using for the web server:

const server = require('http').createServer();
const io = require('socket.io')(server);
io.on('connection', function(socket){
  console.log('a user connected');
  //console.log(socket)
  io.emit('bot_uttered', {"text": "hola, soy jean pierre el servidor"})
  socket.on('user_uttered',function(message){
    console.log(message);
    return true;
  });
  return true;
});


server.listen(3000);

When the client connects the message from the server is sent but im unable to write from the client side.

im suspecting that it has something to do with
initPayload: "/get_started"
but i havent found anywhere what that options is suposed to do.

Thaks!

i am seeing the same behavior..

Using webchat Versions 0.5.3, 0.5.2 or 0.5.0 in a <script> tag

I see client the connection to my Rasa Server and its sending a Session_request event, but it does not appear to be sending the initPayload. ( or at least rasa is not registering it. )
web console is free of errors.
dropping back to webchat version 0.4.2 everything works as expected..

script config

   WebChat.default.init({
   selector: "#webchat",
   initPayload: "utter_greet",
   interval: 1000, // 1000 ms between each message
   socketUrl: "http://test-server:5004",
   socketPath: "/socket.io/",
   title: "Web Chat",
   inputTextFieldHint: "Type a message...",
   connectingText: "Waiting for server...",
   fullScreenMode: false,
   profileAvatar: "http://test-server:8080/images/dhelmet.png",
   hideWhenNotConnected: false,
       params: {
         images: {
             dims: {
           width: 300,
          height: 200,
             }
       },
   storage: "local"
   }
   })
   WebChat.show()

Hope that helps...

Are you able to talk to the bot? Does it answer?

[jeanpah]

@znat No, the input is disabled. but the connection to the server is logged. Im using firefox, the version of the plugin is the latest, im using the script tag.

@colinhobbs Thanks!, this rolling back the js client to version 0.4.2 make it work as expected.

[znat]

Did you set session_persistence: true in the SocketIOInput section of the credentials.yaml file?

[jeanpah]

@znat sorry i'm using only socket.io for the backend, im not using rasa at the moment. but usign version 0.4.2 made the plugin work with a simple echo bot:

const server = require('http').createServer();
const io = require('socket.io')(server);
io.on('connection', function(socket){
  console.log('a user connected');
  //console.log(socket)
  io.emit('bot_uttered', {"text": "hola, soy jean pierre el servidor"})
  socket.on('user_uttered',function(message){
    io.emit('bot_uttered', {"text": message.message})
    return true;
  });
  return true;
});


server.listen(3000);

with rasa.. I do have the session persistence set ..
Rasa config

socketio:
  user_message_evt: user_uttered
  bot_message_evt: bot_uttered
  session_persistence: true

I do see the client request a session.. just not seeing rasa respond at all to that request...

I used @jeanpah config on nodejs and could see the same result.. in looking at the logs i see the client connect. I guess i'm not sure what the client is looking for to confirm it has a connection to the server because you can see the client send the heardbeat ping and pong..

I've resolved this issue recently. This will not be an issue once rasa_core release a new version. 0.12.4+.
For now, the work around is you install a github latest version rasa-core or replace your channels/socketio.py with github latest one.

[jeanpah]

@hrqiang Is there any solution for socket.io?

[dliuproduction]

check issue #28

[jeanpah]

Hi everyone,

I managed to make the plugin work in version 0.5.3 with socket.io. it was fixed by adding two more events to the socket script "session_request, session_confirm":

const server = require('http').createServer();
const io = require('socket.io')(server);
const request = require('request');


io.on('connection', function(socket){
  console.log('a user connected');
  //console.log(socket)

  socket.on('session_request',function(id){
    return id.session_id
  })

  io.emit("session_confirm","hola")
  io.emit('bot_uttered', {"text": "hola, soy jean pierre el servidor"})

  socket.on('user_uttered',function(message){
    bot_data = {
      "object":"page",
      "entry":[
        {
          "messaging":[
            {
              "sender":{"id":"2149648825097538"},
              "recipient":{"id":"654472771621094"},
              "message": {"text":message.message}
            }
          ]
        }
      ]
    }


    var options = {
      uri: 'http://127.0.0.1:8080/messengerBotWebhook',
      method: 'POST',
      json: bot_data
    };
    request(options, (err, res, body) => {
      if (err) { return console.log(err); }
      //console.log(body.url);
      try{
        result = JSON.parse(body);
        console.log(result)
      }catch(e){
        console.log(e)
      }
    });
    io.emit('bot_uttered', {"text": "simon dice "+message.message})
    return true;
  });
  return true;
});


server.listen(3000);

[znat]

Right, of course! Thanks @jeanpah .
Would you consider adding them in the readme in a PR?
