Not able to get responses from luis.ai to bot framework, getting error instead

I started working on bot framework in node.js and used luis.ai for my nlp. Referring the documentation on azure for their botframework for node.js, I did the code changes in app.js. However I am getting the following error when running the code in online editor.

[info] Restarting server... [info] Click on http://firstbot2-b893.azurewebsites.net to open your site restify listening to http://undefined:undefined

Also, a new browser window opens with following error...

code "ResourceNotFound" message "/ does not exist"

Please find the app.js and package.json code below...

app.js

var restify = require('restify');
var builder = require('botbuilder');
var botbuilder_azure = require("botbuilder-azure");

// 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.MicrosoftAppId,
    appPassword: process.env.MicrosoftAppPassword,
    openIdMetadata: process.env.BotOpenIdMetadata 
});

// Listen for messages from users 
server.post('/api/messages', connector.listen());

var tableName = 'botdata';
var azureTableClient = new botbuilder_azure.AzureTableClient(tableName, process.env['AzureWebJobsStorage']);
var tableStorage = new botbuilder_azure.AzureBotStorage({ gzipData: false }, azureTableClient);

// Create your bot with a function to receive messages from the user
//var bot = new builder.UniversalBot(connector);
// Create your bot with a function to receive messages from the user
// This default message handler is invoked if the user's utterance doesn't
// match any intents handled by other dialogs.
var bot = new builder.UniversalBot(connector, function (session, args) {
    session.send('You reached the default message handler. You said \'%s\'.', session.message.text);
});
bot.set('storage', tableStorage);

// Make sure you add code to validate these fields
var luisAppId = process.env.LuisAppId;
var luisAPIKey = process.env.LuisAPIKey;
var luisAPIHostName = process.env.LuisAPIHostName || 'westus.api.cognitive.microsoft.com';

const LuisModelUrl = 'https://' + luisAPIHostName + '/luis/v2.0/apps/' + luisAppId + '&subscription-key=' + luisAPIKey;


// Main dialog with LUIS
var recognizer = new builder.LuisRecognizer(LuisModelUrl);
// Add the recognizer to the bot
bot.recognizer(recognizer);

var intents = new builder.IntentDialog({ recognizers: [recognizer] })
.matches('Greeting', (session) => {
    session.send('You reached Greeting intent, you said \'%s\'.', session.message.text);
})
.matches('Help', (session) => {
    session.send('You reached Help intent, you said \'%s\'.', session.message.text);
})
.matches('Cancel', (session) => {
    session.send('You reached Cancel intent, you said \'%s\'.', session.message.text);
})
.matches('Reports', (session) => {
    session.send('You reached Reports intent, you said \'%s\'.', session.message.text);
})
.onDefault((session) => {
    session.send('Sorry, I did not understand \'%s\'.', session.message.text);
});

//bot.dialog('/', intents);

var bot = new builder.UniversalBot(connector, function (session, args) {
    session.send('You reached the default message handler. You said \'%s\'.', 
        session.message.text);
});

This second parameter counts as a root dialog ('/'), which is why you received the error message regarding the dialog already existing.

You're also plugging the LuisRecognizer into the bot level and then into an IntentDialog:

// Main dialog with LUIS
var recognizer = new builder.LuisRecognizer(LuisModelUrl);
// Add the recognizer to the bot
bot.recognizer(recognizer);

var intents = new builder.IntentDialog({ recognizers: [recognizer] })

You should only use one or the other, especially when starting off and when only using one created LuisRecognizer.

I recommend changing your var bot line to:

var bot = new builder.UniversalBot(connector);

And then using your IntentDialog only with your root dialog, by uncommenting this line:

//bot.dialog('/', intents);

Is there a reason this is commented out:

//bot.dialog('/', intents);

Seems you need to define somewhere for dialog to listen, and matches up with the "/" no resource found error.
