问题
In the following example: If the user says toffee, shouldn't that be translated to candy? I ask because the value handed to my intent is 'toffee'. So not sure what I have incorrect.
types":[
{
"name":"SHOPPING_LIST",
"values":[
{
"id":null,
"name":{
"value":"candy",
"synonyms":[
"toffee"
]
}
},
{
"name":"GetPrice",
"samples":[
"Get me the price of {item}",
"tell me the price of {item}",
],
"slots":[
{
"name":"item",
"type":"SHOPPING_LIST"
}
]
}

We need to handle the entity resolution in your backend code. More can be referred here: https://developer.amazon.com/blogs/alexa/post/5de2b24d-d932-4c6f-950d-d09d8ffdf4d4/entity-resolution-and-slot-validation
In your code you can add,
this.attributes.item = slotValue(this.event.request.intent.slots.item);
Also, add this outside your handler function,
function slotValue(slot, useId){
let value = slot.value;
let resolution = (slot.resolutions && slot.resolutions.resolutionsPerAuthority && slot.resolutions.resolutionsPerAuthority.length > 0) ? slot.resolutions.resolutionsPerAuthority[0] : null;
if(resolution && resolution.status.code == 'ER_SUCCESS_MATCH'){
let resolutionValue = resolution.values[0].value;
value = resolutionValue.id && useId ? resolutionValue.id : resolutionValue.name;
}
return value;
}
Now when your user enters toffee, it will be translated to candy.

The general response JSON structure would be as follows, so to extract it in a line use
source = intent.slots.source.resolutions.resolutionsPerAuthority[0].values[0].value.name;
"request": {
"type": "IntentRequest",
"requestId": "amzn1.ech****************************************************************************************",
"timestamp": "2019-03-13T08:34:46Z",
"locale": "en-US",
"intent": {
"name": "STMDStreamStartIntent",
"confirmationStatus": "NONE",
"slots": {
"source": {
"name": "source",
"value": "source 1",
"resolutions": {
"resolutionsPerAuthority": [
{
"authority": "amzn1.er-authority.e************************************************",
"status": {
"code": "ER_SUCCESS_MATCH"
},
"values": [
{
"value": {
"name": "source1",
"id": "SOURCE_ONE"
}
}
]
}
]
},
"confirmationStatus": "NONE",
"source": "USER"
}
}
}
}
Hope this would be simple and helpful.
