I have been implementing CanfulFillIntentRequest for many days, but no luck so far. I am using alexa-sdk-nodejs v2. I am not able to build the response for CanfulFillIntent. I tried implementing it in an exact way as stated in these documents.
https://developer.amazon.com/docs/custom-skills/understand-name-free-interaction-for-custom-skills.html
https://developer.amazon.com/docs/custom-skills/implement-canfulfillintentrequest-for-name-free-interaction.html.
This is my response handler .
return handlerInput.responseBuilder
.withCanFulfillIntent(
{
'canFulfill': 'MAYBE',
'slots':{
}
})
.getResponse();
}
const HelloWorldIntentHandler = {
canHandle(handlerInput) {
//return handlerInput.requestEnvelope.request.type === 'IntentRequest' || 'CanFulfillIntentRequest'
return handlerInput.requestEnvelope.request.type === 'CanFulfillIntentRequest'
// && handlerInput.requestEnvelope.request.intent.name === 'Myname' || 'HotelIntent';
},
handle(handlerInput) {
if(handlerInput.requestEnvelope.request.intent.name === 'Myname'){
return MynameHandler.handle(handlerInput);
}
};
When i run JSON code in manual JSON, It does not respond to the CanfulFillIntent request and it gets redirected to error handler code.

The withCanFulfillIntent() response builder helper method is only available in ASK SDK for Node.js (Public Beta)
Install public beta by
npm install --save ask-sdk-model#beta
npm install --save ask-sdk-core#beta
or use this in package.json
"dependencies": {
"ask-sdk-core": "^2.1.0-beta.1",
"ask-sdk-model": "^1.4.0-beta.1"
}
I tried your code with beta and got expected results:
{
"version": "1.0",
"response": {
"outputSpeech": {
"type": "SSML",
"ssml": "<speak>ALex</speak>"
},
"reprompt": {
"outputSpeech": {
"type": "SSML",
"ssml": "<speak>Please respond</speak>"
}
},
"shouldEndSession": false,
"canFulfillIntent": {
"canFulfill": "YES"
}
},
"userAgent": "ask-node/2.1.0-beta.4 Node/v8.10.0",
"sessionAttributes": {
"key": "string value"
}
}
