Bot dialog doesn't start

Question

i'm here to ask of any of you guys know why my bot won't start the dialog? I'm a new guy in the world of bots and read a lot of it, but can't seem to fix this.

var restify = require('restify');
var builder = require('botbuilder');

// Setup Restify Server
var server = restify.createServer();
server.listen(process.env.port || process.env.PORT || 3978, function () {
   console.log('%s listening to %s', server.name, server.url);
});

// Create chat connector for communicating with the Bot Framework Service
var connector = new builder.ChatConnector({
    appId: process.env.MICROSOFT_APP_ID,
    appPassword: process.env.MICROSOFT_APP_PASSWORD
});


var luisAppUrl = process.env.LUIS_APP_URL || 'https://westus.api.cognitive.microsoft.com/luis/v2.0/apps/.......';
var bot = new builder.UniversalBot(connector);

var bot = new builder.UniversalBot(connector, function(session, args, next) {
  session.send('How can i help you ?')
  session.endDialog();
  next();
});

bot.recognizer(new builder.LuisRecognizer(luisAppUrl));


bot.dialog('Location', [
  function (session, args, next) {
  var intent = args.intent;
    var locations = builder.EntityRecognizer.findEntity(intent.entities, 'Location');
     var location = session.dialogData.location = {
       title: title
     };
    // session.send()
    if (!locations){
      builder.Prompts.text(session, 'From which settlement do you want to know the location? ')
    } else {
      next();
    }

  },
  function(session, results) {
    var location = session.dialogData.location;
    if(results.response){
      note.text = results.response;
      // session.send('Our company is located in Antwerp')
    }
  }
]).cancelAction({
  matches: /^(cancel|nevermind)/i,
  confirmPrompt: "Are you sure?"
});

So my bot just keeps crashing and doesn't start the bot.dialog ? Can you guys see what is wrong ?

Answer 1

The bot is crashing because you're instantiating the UniversalBot class twice:

var luisAppUrl = process.env.LUIS_APP_URL // etc
var bot = new builder.UniversalBot(connector);

var bot = new builder.UniversalBot(connector, function(session, args, next) {
  session.send('How can i help you ?')
  session.endDialog();
  next();
});

Try removing the first bot so your code is just:

var luisAppUrl = process.env.LUIS_APP_URL // etc

var bot = new builder.UniversalBot(connector, function(session, args, next) {
  session.send('How can i help you ?')
  session.endDialog();
  next();
});

EDIT:

To reach the 'Location' dialog, you'll need to add a triggerAction() to your dialog .

bot.dialog('Location', [
  function (session, args, next) {
    // ...
  },
  function(session, results) {
    // ...
  }
]).triggerAction({
  matches: 'Location' // What your intent from LUIS is called.
}).cancelAction({
  matches: /^(cancel|nevermind)/i,
  confirmPrompt: "Are you sure?"
});
