在 AWS Lambda function 中获取插槽的问题

Question

I am trying to build a simple Alexa Skill. Now, I want to access some of my slot values. This is my code. When I uncomment even the line that I define Alexa in, my skill will not work. Also, if I only uncomment the line defining var text, I still get "there was a problem with the skills response". Const gives the same output. I am using custom slots called recipe. How can I access the slots in my lambda function? Thanks.

 const breakfast = { "bacon and eggs":["bacon","egg"], "buttered toast":["bread", "butter"] }; const lunch = { "ham sandwich":["ham","cheese"] }; const dinner = { "Steak and eggs": ['steak','eggs']}; //const Alexa = require('ask-sdk-core'); exports.handler = (event, context, callback) => { try { if (event.request.type === 'LaunchRequest') { callback(null, buildResponse('Hello from Lambda')); } else if (event.request.type === 'IntentRequest') { const intentName = event.request.intent.name; if (intentName === 'breakfast') { callback(null, buildResponse(Object.keys(breakfast)+"") ); } else if (intentName === 'lunch') { callback(null, buildResponse(Object.keys(lunch)+"") ); } else if (intentName === 'dinner') { callback(null, buildResponse(Object.keys(dinner)+"") ); } else if (intentName ==='requestRecipe'){ //var text = this.event.request.intent.slots.recipe.value; //const meal = Alexa.getSlotValue(intentName, "meal") callback(null, buildResponse("Recipe requested") ); } else { callback(null, buildResponse("Sorry, i don't understand")); } } else if (event.request.type === 'SessionEndedRequest') { callback(null, buildResponse('Session Ended')); } } catch (e) { context.fail(`Exception: ${e}`); } }; function buildResponse(response) { return { version: '1.0', response: { outputSpeech: { type: 'PlainText', text: response, }, shouldEndSession: false, }, sessionAttributes: {}, }; }

for a bit of context: my lambda has the endpoint of what my alexa hosted skill was, and the alexa skill has the endpoint of the lambda. when I say const gives the same output, i mean instead of using var, when I use const, it does the same thing. The JSON file that i get as a reply is empty brackets.

I found the issue behind my problem. Instead of using
//var text = this .event.request.intent.slots.recipe.value; i simply did var text = event.request.intent.slots.recipe.value; I am now able to use text in building a response or something like that.
