Alexa not invoking the Intent

Question

I was trying to make an alexa skill, which is based on the fact skill of the alexa's blueprint. I've made a custom Intent named "myIntent", which has a variable "{myName}" or slot type "myNameSlot". I've added multiple values like "Dhruv,User,My User" (all are separate values).

So, I tried to launch my Alexa skill in Test via the simulator. It is launching all the in-built intents just fine. However, when I try to launch my custom Intent, it doesn't launch.I wrote the same utterances, however, it is not being invoked.

Here's my Lambda Function's code : https://pastebin.com/7CrdMffW

exports.handler = function (event, context, callback) {
    const alexa = Alexa.handler(event, context, callback);
    alexa.APP_ID = APP_ID;
    alexa.registerHandlers(handlers);
    alexa.execute();
};

I'm not sure what's happening here.

EDIT: This is the information about my Intent and custom slot :

Intent Name : myIntent.

Utterances :

1.) tell me about {data_of_intent}

2.) what is the synopsys of {data_of_intent}

Intent Slots (1) : data_of_intent of type my_custom_type.

Custom Slot Type Values :

1.) one piece

2.) Flower Dream

3.) Kanai kun

4.) Has the rain stopped?

Answer 1

I double checked the JSON I was receiving on the first hit.The issue was that shouldEndSession was set to true and that's because, in NodeJS, shouldEndSession is set to true in :tell and cannot be overridden.

I was using :

this.emit(':tell', '2 Hello, what would you like to do?');.

I changed it to :

this.emit(':ask', '2 Hello, what would you like to do?');

and it worked.

There's a Github thread for the same : https://github.com/alexa/alexa-skills-kit-sdk-for-nodejs/issues/64
