I keep getting an error when I try to test my basic skill (I'm trying to learn how to create them).
Here is the error from the log:

2018-11-21T16:10:55.759Z 06a36441-eda8-11e8-a421-f996bf66c592
Unexpected exception 'TypeError: Cannot read property 'value' of

at exports.handler (/var/task/index.js:52:9)

How can I figure this out?

Here is my code:

var Alexa = require('alexa-sdk');





const APP_ID = 'amzn1.ask.skill.ab07421a-0a92-4c2b-b3bd-998e14286xxx';





const skillData = [

    {

        city: "Austin",

        suggestion: "Austin has some of the most outstanding people."

    },

    {

        city: "San Antonio",

        suggestion: "San Antonio has some of the most outstanding people."    

    },

    {

        city: "Dallas",

        suggestion: "The Dallas metroplex is one of the hottest places."

    }

];





var number = 0;

while(number<3){

var handlers = {

  'LaunchRequest': function () {





      this.emit(':ask', 'Tell me the name of the major city you are closest to'

   },

  'Unhandled': function () {

      this.emit(':ask', 'Try saying a city name like Austin, San Antonio, or Dallas'); 

  },

  'getSuggestion': function() {

      var city = this.event.request.intent.slots.City.value;





      this.emit(':ask', getSuggestion(skillData,'city', city.toUpperCase()).suggestion + '. Give me another city and I'll hook you up with the best peeps.');

  },

  'AMAZON.HelpIntent': function () {

      this.emit(':ask', "What can I help you with?", "How can I help?");

  },

  'AMAZON.CancelIntent': function () {

      this.emit(':tell', "Okay!");

  },

  'AMAZON.StopIntent': function () {

      this.emit(':tell', "Goodbye!");

  },

};

number = number+1;

}





exports.handler = function(event, context, callback){

  var alexa = Alexa.handler(event, context);

  alexa.appId = APP_ID;

  alexa.registerHandlers(handlers);

  alexa.execute();

};





function getSuggestion(arr, propName, cityName) {

  for (var i=0; i < arr.length; i++) {

    if (arr[i][propName] == cityName) {

      return arr[i];

    }

  }

}

Update

I've made some changes that were suggested below, however, I am still getting an error after the initial response.

"errorMessage": "Cannot read property 'city' of undefined"

Please look at my new code and help me figure this out:

var Alexa = require('alexa-sdk');



const APP_ID = 'amzn1.ask.skill.ab07421a-0a92-4c2b-b3bd-998e14286xxx';

        suggestion: "Austin is blahblahblahblahlshflashdfasldfha blah."

    },

    {

        city: 'San Antonio',

        suggestion: "San Antonio has blahblahblahblahlshflashdfasldfha blah."    

    },

    {

        city: 'Dallas',

        suggestion: "The Dallas metroplex is one of the hottest blahblahblahbla blahblahblahblahblahblah."

    }

];



var number = 0;

while(number<3){

var handlers = {

      this.emit(':ask', 'Tell me the name of the major city you are closest to!', 'Which major city are you closest to?');

  'Unhandled': function () {

      this.emit(':ask', "Try saying a city name like Austin, San Antonio, or Dallas"); 

  },

  'getSuggestion': function() {

      var city = this.event.request.intent.slots.city.value;



      this.emit(':ask', getSuggestion(skillData,'city', city.toUpperCase()).suggestion + '. Give me another city and I'll hook you up with the best peeps.');

  },

      this.emit(':tell', "Goodbye!");

  },

};



number = number+1;

}

exports.handler = function(event, context, callback){

  var alexa = Alexa.handler(event, context);

  alexa.appId = APP_ID;

  alexa.registerHandlers(handlers);

  alexa.execute();

};



function getSuggestion(arr, propName, cityName) {

  for (var i=0; i < arr.length; i++) {



    var prop = arr[i][propName];

    prop = prop.toUpperCase();



    if (prop == cityName) {

      return arr[i];

    }

  }

}

ok. alexa-sdk has been deprecated link. To get the new SDK, do this.

1 - Create a new function in Lambda.

2 - Choose AWS Serverless Application Repository.

3 - Choose alexa-skills-kit-nodejs-factskill.

4 - Click on deploy. Once deployed, click on functions and you should see the new function you just created with a name like aws-serverless-repository-alexaskillskitnodejsfact-NR8HPILH8WNI.

5 - Delete the code and replace the code with this.

const Alexa = require('ask-sdk');    

    const skillData = [

                {

                    city: 'Austin',

                },

                {

                    city: 'San Antonio',

                    suggestion: "San Antonio has blahblahblahblahlshflashdfasldfha blah."    

                },

6 - Go to developer.amazon.com and change your Alexa Skill endpoint to the new lambda ARN.

Hope this helps.
