How retrieve intent slot value, drive me crazy - aws-lambda

Question

I simply want to retrieve to slot value on code, I wanna try to do a simple skill who respond in different ways according to day sopeak from users.
This is my sample code, I'm trying in blank project for don't have other issue.
The intent is "HelloWorldIntent" the slot is "day"
JSON:
{
"interactionModel": {
"languageModel": {
"invocationName": "try",
"intents": [
{
"name": "AMAZON.CancelIntent",
"samples": []
},
{
"name": "AMAZON.HelpIntent",
"samples": []
},
{
"name": "AMAZON.StopIntent",
"samples": []
},
{
"name": "HelloWorldIntent",
"slots": [
{
"name": "day",
"type": "AMAZON.DayOfWeek"
}
],
"samples": [
"good {day}",
"hello",
"how are you",
"say hi world",
"say hi",
"hi",
"say hello world",
"say hello"
]
},
{
"name": "AMAZON.NavigateHomeIntent",
"samples": []
}
],
"types": []
}
}
}
The index.js is:
const HelloWorldIntentHandler = {
canHandle(handlerInput) {
return handlerInput.requestEnvelope.request.type === 'IntentRequest'
&& handlerInput.requestEnvelope.request.intent.name === 'HelloWorldIntent';
},
handle(handlerInput) {
var app = this.event.request.intent.slots.day.value;
const speechText = app;
return handlerInput.responseBuilder
.speak(speechText)
//.reprompt('add a reprompt if you want to keep the session open for the user to respond')
.getResponse();
}
};
When I ask good Monday (or any other day) the result is Sorry, I couldn't understand what you said. Please try again.
Any suggestion?

Answer 1

This is your issue:
var app = this.event.request.intent.slots.day.value;
That looks like code for the v1 of the SDK.
It looks like you're actually using v2 - if you have the most recent version, to get a slot value you can do this:
// Require the SDK at the top of your file
const Alexa = require('ask-sdk');
// Then in your handle function where you want the slot value
handle (handlerInput) {
const { requestEnvelope } = handlerInput;
const speechText = Alexa.getSlotValue(requestEnvelope, 'day');
return handlerInput.responseBuilder.speak(speechText).getResponse();
}
Alternatively, you could also get it like this:
const speechText = handlerInput.requestEnvelope.request.intent.slots['day'].value
