我在 Dialogflow 上的 webhook 没有响应

Question

This is the code I have in my server:

const express = require('express');
const bodyParser = require('body-parser');

const appExpress = express().use(bodyParser.json());

const {
  dialogflow,
  Image,
} = require('actions-on-google')

const app = dialogflow()

appExpress.post('/hook', express.json() ,(req, res) => {

  app.intent('MyIntent', conv => {
    conv.ask('Hi, how is it going?')
  });

});

appExpress.listen(3333, ()=>console.log("Server is live at port 3333"));

When I run this, it returns no errors (I see the message "server is live..") and also when I send a message to my bot with the intent "MyIntent" I get no error, but also no response..

If I look at the Diagnostic Info, under the Fulfillment Status there is this error:

Webhook call failed. Error: DEADLINE_EXCEEDED.

What am I doing wrong?

I don't know how that google library is supposed to work, but generally when using express, you most close the HTTP request by sending a response, there are several examples here

You could try adding this after convo.ask

res.sendStatus(200);
