I have an interaction model with a GetMenuIntent which I can invoke with "what's for {meal}". meal is a MealType custom slot with allowed values of "breakfast" and "lunch". I added validation on the meal slot in my GetMenuIntent to only allow those values defined in the slot type and it works great for those configured values.
However, after saving and building my model, when I put "what's for dinner" into the Utterance Profiler or the interactive tester, It ended up calling my FallbackIntent instead of reprompting for a correct value.
I feel like what I'm trying to do isn't really much different than Amazon's own example here.
Here's "whats for lunch" working correctly:
And here's "whats for dinner" ignoring my GetMenuIntent and calling FallbackIntent instead:
Here's my interaction model:

Since this is 6 months old I assume you figured out by now that your interaction model only includes Lunch and Breakfast.
During Alexa discovery process, we need to send device details and their capabilities. I am sending light and fan details. Light gets showed up in Alexa App but not the fan. Can you please help me to find what I am doing wrong with the following response.

Note: I am just repeating above question below because StackOverflow doesn't allow so much code to be pasted with less description.
During Alexa discovery process, we need to send device details and their capabilities. I am sending light and fan details. Light gets showed up in Alexa App but not the fan. Can you please help me to find what I am doing wrong with the following response.
I think Alexa.RangeController is currently restricted to US region. So if you are trying to discover devices registered to account outside US, then it looks like that Alexa simply ignores the discovery response with RangeController interface. The way I got around this problem is by switching the user account to US and the device appeared immediately. Give it a try and if you a better solution then please do share.
I was playing around with the proactive events but got stuck at the localizedattribute thing. So I was using media content available schema and it has two localizedattribute, and I can't find an example on how to use two of them at once. Any idea? So basically, this works :
{
"timestamp": "2019-01-25T08:41:01.00Z",
"referenceId": "orangfdetango2221800f44-436a-4c47-8d9f-e14356bb010c",
"expiryTime": "2019-01-26T08:20:01.00Z",
"event": {
"name": "AMAZON.MediaContent.Available",
"payload": {
"availability": {
"startTime": "2019-01-23T21:00:00Z",
"method":"DROP"
},
"content": {
"name": "localizedattribute:contentName",
"contentType":"EPISODE"
}
}
},
"localizedAttributes": [
{
"locale": "en-US",
"contentName": "Who Wrote the Bible? - 01/13/2019"
}
],
"relevantAudience": {
"type": "Multicast",
"payload": {}
}
}
But not this because it has two localizedattributes:
{
"timestamp": "2019-01-25T08:41:01.00Z",
"referenceId": "orangfdetango2221800f44-436a-4c47-8d9f-e14356bb010c",
"expiryTime": "2019-01-26T08:20:01.00Z",
"event": {
"name": "AMAZON.MediaContent.Available",
"payload": {
"availability": {
"startTime": "2019-01-25T21:00:00Z",
"provider": {
"name": "localizedattribute:providerName"
},
"method":"STREAM"
},
"content": {
"name": "localizedattribute:contentName",
"contentType":"EPISODE"
}
}
},
"localizedAttributes": [
{
"locale": "en-US",
"providerName": "Lindsborg Covenant Church"
},
{
"locale": "en-US",
"contentName": "Who Wrote the Bible? - 01/13/2019"
}
],
"relevantAudience": {
"type": "Multicast",
"payload": {}
}
}
Apparently, it was a simple fix, though I couldn't find it in any documentation.
What needed to be done was changing localized attributes to:
"localizedAttributes": [
{
"locale": "en-US",
"providerName": "Lindsborg Covenant Church",
"contentName": "Who Wrote the Bible? - 01/13/2019"
}
],
so I have written a handler for an intent where the user asks Alexa to recommend a service i.e. "Alexa could you recommend a plumber". The problem is that Alexa comes in an triggers its default recommendation action.
The conversation is as follows:
User: Alexa open Bucharest insight
Alexa: Hi, welcome to Bucharest Insight, how are you? you can ask me questions about the local news or ask me for a recommendation.
User: I need a plumber
Alexa: Here are a few top-rated ones
I was expecting my getRecommendationIntentHandler to be triggered as I have setup the intent correctly ( See the below JSON) - "I need a {serviceName}",
The result from Alexa seems like a build in response instead of my custom intent handler below:
const getRecommendationIntentHandler = {
canHandle(handlerInput) {
return handlerInput.requestEnvelope.request.type === 'IntentRequest'
&& handlerInput.requestEnvelope.request.intent.name === 'getRecommendationIntent';
},
handle(handlerInput) {
console.log('Called getRecommendationIntentHandler');
const responseBuilder = handlerInput.responseBuilder;
const filledSlots = handlerInput.requestEnvelope.request.intent.slots;
// Get the filled slots inputted by the user
const slotValues = getSlotValues(filledSlots);
console.log(JSON.stringify(slotValues));
const speechText = 'getRecommendationIntentHandler called';
return responseBuilder
.speak(speechText)
.getResponse();
},
};

Your first response does not have shouldEndSession parameter. If not provided, defaults to true. What that means is that, once your response is read, Alexa will end the session and closes the skill. You are no longer inside the skill. Whenever you want Alexa to wait for user response, keep the session alive by setting shouldEndSession parameter set to false.
Your first response should be like this:
{
"body": {
"version": "1.0",
"response": {
"outputSpeech": {
"type": "SSML",
"ssml": "<speak>Hi, welcome to Bucharest Insight, how are you ? you can ask me questions about the local news or ask me for a recommendation</speak>"
},
"shouldEndSession": false
},
"sessionAttributes": {},
"userAgent": "ask-node/2.0.5 Node/v8.10.0"
}
}
The good thing is that, you don't have to set this parameter manually and the SDK will take care of it. For that use a reprompt. Including a reprompt in your response is a good design.
return responseBuilder
.speak(speechText)
.reprompt(repromptSpeechOutput)
.getResponse();
If you don't want to use a reprompt you can use withShouldEndSession(false).

I'm trying to develop an Alexa skill, and I need to get the relative time, eg: "5 minutes ago".
I have defined a time slot for my skill which accepts time like 5 minutes, 6.30 am or 4 in the morning. But I'm not able to accept a time like 5 minutes ago. I new to Alexa and can some one help me out with this
{
"slots": [
{
"name": "time",
"type": "AMAZON.TIME"
}
],
"intent": "ReportTime"
}
You could add a {modifier} slot that can take several keywords like "ago" and "from now". The intent could then have something like the following utterances:
{
"name": "TimeTest",
"samples": [
"what happened {time} {modifier}",
"what will happen {time} {modifier}"
],
"slots": [
{
"name": "time",
"type": "AMAZON.TIME",
"samples": []
},
{
"name": "modifier",
"type": "custom_time_modifier",
"samples": []
}
]
}
with the following custom modifier type:
"types": [
{
"name": "custom_time_modifier",
"values": [
{
"id": null,
"name": {
"value": "ago",
"synonyms": [
"in the past"
]
}
},
{
"id": null,
"name": {
"value": "from now",
"synonyms": [
"in the future"
]
}
}
]
}
