Node.js 在dialogflow中执行POST请求

我试图使用DialogFlow的内联编辑器对GitHub的API进行HTTP post调用。这是我的密码：

// See https://github.com/dialogflow/dialogflow-fulfillment-nodejs
// for Dialogflow fulfillment library docs, samples, and to report issues
'use strict';

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

var github = require('request');
github.post({
  headers: {'User-Agent' : 'dummy-gh-user', 'Authorization': 'token ****'},
  url:     'https://api.github.com/repos/dummy-gh-user/dummy-gh-repo/issues',
  json:    
  {
  "title": "This is a bug",
  "body": "I'm having a problem with this.",
  "assignees": [
    "dummy-gh-user"
  ],
  "labels": [
    "bug"
  ]
}
}, function(error, response, body){
  console.log(body);
});

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);
});

上面的代码得到部署和保存，我在firebase控制台中没有发现任何错误。

虚拟gh用户

将替换为我的github用户名。我已将我的代码添加到现有的完整填充代码中

关于这段代码为什么不起作用有什么想法吗？

github帖子的代码在我的本地环境中运行得非常好。不确定发生了什么变化。但同样的代码今天也在起作用。
