Я получаю сообщение об ошибке, когда пытаюсь проверить свои базовые навыки (я пытаюсь научиться их создавать).Вот ошибка из журнала:
2018-11-21T16: 10: 55.759Z 06a36441-eda8-11e8-a421-f996bf66c592 Неожиданное исключение 'Ошибка типа: не удалось прочитать значение' значения 'из неопределенного значения':
TypeError: Невозможно прочитать свойство 'value' undefined в Object.getSuggestion (/var/task/index.js:31:54) в emitNone (events.js: 86: 13) в AlexaRequestEmitter.emit(events.js: 185: 7) в AlexaRequestEmitter.EmitEvent (/var/task/node_modules/alexa-sdk/lib/alexa.js:216:10) в AlexaRequestEmitter.ValidateRequest (/ var / task / node_modules / alexa-sdk)/lib/alexa.js:181:23) в AlexaRequestEmitter.HandleLambdaEvent (/var/task/node_modules/alexa-sdk/lib/alexa.js:126:25) в AlexaRequestEmitter.value (/ var / task / node_modules / alexa)-sdk / lib / alexa.js: 100: 31)

Как определитьэто вышло?
Вот мой код:
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: "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'

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) {

}
}
Обновление
Я внес некоторые изменения, которые были предложены ниже, однако я все еще получаю ошибкупосле первоначального ответа.
"errorMessage": "Невозможно прочитать свойство 'city' undefined"
Пожалуйста, посмотрите мой новый код и помогите мне разобраться:

ОБНОВЛЕНИЕ # 2
После долгих попыток разных вещей, я приобрел навык бега с помощью Бала Симпсона!
Тем не менее, умение по-прежнему выдает ошибку, когда пользователь произносит название города.В моей модели взаимодействия должна быть ошибка:
