I tried to connect my existing firestore database to Dialogflow fulfillment. The function deployed to Google CLoud Function successfully but I cannot add data to my database. I have tried to change the node version 8 but still failed. Please help me.

Index.js

'use strict';
const admin = require('firebase-admin');
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');
   

  admin.initializeApp({
   apiKey: "Axxxx",
    authDomain: "/xxxxx.firebaseio.com",
    databaseURL: "https:/xxxxxx.firebaseio.com",
    projectId: "mxxxxx8",
    storageBucket: "xxxxx.com",
  });

  const functions = require('firebase-functions');
  const settings = {timestampsInSnapshots: true};
  var db = admin.firestore();
  admin.firestore().settings({ timestampsInSnapshots: true });
 
process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements
 
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
  const agent = new WebhookClient({ request, response });
  console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
  console.log('Dialogflow Request body: ' + JSON.stringify(request.body));
 
  function welcome(agent) {
    agent.add(`Welcome to my agent!`);
  }
 
  function fallback(agent) {
    agent.add(`I didn't understand`);
    agent.add(`I'm sorry, can you try again?`);
  }
  

  // Run the proper function handler based on the matched Dialogflow intent name
  let intentMap = new Map();
  intentMap.set('Default Welcome Intent', welcome);
  intentMap.set('Default Fallback Intent', fallback);
  // intentMap.set('your intent name here', yourFunctionHandler);
  // intentMap.set('your intent name here', googleAssistantHandler);
  agent.handleRequest(intentMap);
});

推荐答案

解决方案是将Firebase项目计划升级为Blaze Plan.然后在该Firebase项目下创建一个新的Dialogflow代理.

The solution is upgrade your Firebase project plan to Blaze Plan. Then make a new Dialogflow agent under that Firebase project.
