Webhook呼叫失败。请求超时

Question

我试图在此处实现实现以获取用户数据，但是使用初始Web钩子实现进行测试，以检查是否实现了实现。但是当我以欢迎的意图进行测试时，它会抛出请求超时。 我想知道为什么我会收到此错误？如何解决此错误

'use strict';
 const {dialogflow} = require('actions-on-google'); 
 const functions = require('firebase-functions');
 const {WebhookClient} = require('dialogflow-fulfillment');
 const {Card, Suggestion} = require('dialogflow-fulfillment');

 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));

const app = dialogflow({debug: true});

app.intent('Default Welcome Intent', (conv) => {
 conv.ask('Welcome to action snippets! Say a number.');
});

 //function welcome(agent) {
 // agent.ask(`hii, how can i help you?`);
 //}

 function fallback(agent) {
 agent.add(`I didn't understand`);
 agent.add(`I'm sorry, can you try again?`);
}

当我通过正常的函数调用实现app.intent时：

功能欢迎（代理）...... 它成功运行

  

预期输出应为：

     

嗨，我能为您提供什么帮助？
