question

It's request.intent.slots Not Intent.Slot Case matters, and you are missing an S from slots

I have exactly what you said, "intent.slots.User.value" But no luck.

Make sure that you have properly set up your Intent Schema and Sample Utterances in the developer console. An example of this along with instructions for creating an Alexa skill using lambda can be found here: https://developer.amazon.com/appsandservices/solutions/alexa/alexa-skills-kit/docs/developing-an-alexa-skill-as-a-lambda-function#Testing%20the%20Sample%20with%20an%20Echo%20Device.

Make sure you're passing 'intent' into your function as an argument.

I found this trying to answer the same question / problem. It sounds like I was stuck like you and I gave up. However, I started another test / example and realized that I forgot about the values listed for the custom slot list. So in the "Skills > interaction model > intent schema" you might have: ... "intent": "RecipeIntent", "slots": [ { "name" : "Item", "type": "LIST_OF_ITEMS" } ... but in the "Custom Slot Types" section below you lave to list allowed values for the LIST_OF_ITEMS type. If / when the value you're trying to respond to isn't listed there, it probably won't be recognized as a valid value and won't be treated as a valid/known value. You can see this exchange under the "Skills > interaction model > test" tab. You enter "your keyphrase" hit "enter / click "Ask SkillName" to process the request. Under the "Lambda Request" there should be a section like ... "slots": { "Item": { "name": "Item", "value": "your keyphrase" } } ... where "your keyphrase" is the value you're looking for, [b]BUT[/b] without "your keyphrase" is not in the LIST_OF_ITEMS value list, you'll see a "Lambda Request" like this: ... "slots": { "Item": { "name": "Item" } } ... So, your "Item" slot is set, but the value property isn't and everything appears broken. Thought I'd share what my problem was. Hopefully you and others will be able to save yourselves some time. 8)
