Question

我一直在尝试将在AWS Lambda上运行的Alexa app技能连接到Cloud Firestore，因此我可以从Firestore DB执行一些读写操作。

我在堆栈溢出时遇到了其他问题并遵循了他们推荐的步骤，但每次执行该函数时都失败了。我做错了吗？

任何帮助或指向正确的方向都将是伟大的。

'use strict';
const Alexa = require('alexa-sdk');
const firebase = require('firebase-admin');
const APP_ID = '---';

const SKILL_NAME = '----';
const HELP_MESSAGE = '---';
const HELP_REPROMPT = '----';
const STOP_MESSAGE = '---';

module.exports.Test = (event, context, callback) => {

    context.callbackWaitsForEmptyEventLoop = false;

    if (firebase.apps.length == 0) {
        firebase.initializeApp({
            credential: firebase.credential.cert('---'),
            databaseURL: "---"
        });
    }

    var db = firebase.firestore();
    var docRef = db.collection('users')
        .doc('alovelace');

    var setAda = docRef.set({
        first: 'Ada',
        last: 'Lovelace',
        born: 1815
    });
};

const handlers = {
    'LaunchRequest': function () {
        this.emit('BasicFunction');
    },
    //Help
    'AMAZON.HelpIntent': function () {
        const speechOutput = HELP_MESSAGE;
        const reprompt = HELP_REPROMPT;

        this.response.speak(speechOutput)
            .listen(reprompt);
        this.emit(':responseReady');
    },
    //Cancel
    'AMAZON.CancelIntent': function () {
        this.response.speak(STOP_MESSAGE);
        this.emit(':responseReady');
    },
    //Stop
    'AMAZON.StopIntent': function () {
        this.response.speak(STOP_MESSAGE);
        this.emit(':responseReady');
    },
};

exports.handler = function (event, context, callback) {
    const alexa = Alexa.handler(event, context, callback);
    alexa.APP_ID = APP_ID;
    alexa.registerHandlers(handlers);
    alexa.execute();
};
