使用Dialogflow在Google App上的主机操作在自托管HTTPS服务器上使用节点JS（MalformedResponse：Webhook错误（206））

Question

I have created one app in actions on google with dialogflow using nodejs. First it is hosted on heroku server, but now i want to host in my server with https.

it works properly on heroku server but not working on my server. It returns error "MalformedResponse: Webhook error (206)"

const express = require('express');
const bodyParser = require('body-parser');
var https = require('https');
var fs = require('fs');
const {
  dialogflow,
} = require('actions-on-google');

const app = dialogflow();
const expressApp = express().use(bodyParser.json());

// degault welcome intent on startup
app.intent('Default Welcome Intent', conv => {  
    conv.ask('Hi, Ask me about Customer Ledger, Outstanding....');
});

app.intent('Default Fallback Intent', conv => {
  conv.ask('I didnt understand. Can you tell me something else?');
});


var options = {
  key: fs.readFileSync('ssl/office.key'),
  cert: fs.readFileSync('ssl/office.crt')
};

var server = https.createServer(options, expressApp).listen(3000, function(){
    //express().use(bodyParser.json(), app);
    expressApp.post('/fulfillment', app);
  console.log("Express server listening on port 3000" );
});

Can anyone suggest me what is the problem with my code? Simulator Screenshot

如果您正在使用express并且中间没有其他层（如Heroku所有）将请求从端口443转发到3000，则请求可能无法到达目标端口
