I have to share information from my chatbot working on dialogflow to a human team using SMS. I am using fullfilment to trigger twilio to use my twilio number to send a SMS to the team phone number.

The code is as below

'use strict';
 
const functions = require('firebase-functions');
const {WebhookClient} = require('dialogflow-fulfillment');
const accountSid = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX'; 
const authToken = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX';
const twilio = require('twilio')(accountSid, authToken);

function enviarmensagem(usuario){
    // Configurações da transmissão
const client = new twilio(accountSid, authToken);
    client.messages
      .create({
          body: 'Teste OK',
          to: '+55XXXXXXXXXX',  // Envie uma mensagem a esse número
          from: '+1XXXXXXXXXXX' // Através do meu número Twilio
      })
     .then((message) => console.log(message.sid));
}
  
// Criação da Função no Firebase
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {

  // Definição do objeto controlador do 'agent'
  const agent = new WebhookClient({ request, response });

 // 'Handler' para enviar mensagem
  function enviarmensagem(agent) {
    agent.add('Mensagem enviada');
    enviarmensagem(agent.session);
  }
  
  // Executar a função adequada de acordo com a Intent recebida
  let intentMap = new Map();
  intentMap.set('Teste mensagem', enviarmensagem);

  try{
    agent.handleRequest(intentMap);
  }
  catch(e){
      console.log(e);
  }
});

PACKAGE.JSON

{
  "name": "dialogflowFirebaseFulfillment",
  "description": "This is the default fulfillment for a Dialogflow agents using Cloud Functions for Firebase",
  "version": "0.0.1",
  "private": true,
  "license": "Apache Version 2.0",
  "author": "Google Inc.",
  "engines": {
    "node": "10"
  },
  "scripts": {
    "lint": "semistandard --fix \"**/*.js\"",
    "start": "firebase serve --only functions:dialogflowFirebaseFulfillment",
    "deploy": "firebase deploy --only functions:dialogflowFirebaseFulfillment"
  },
  "dependencies": {
    "actions-on-google": "^2.2.0",
    "firebase-admin": "^5.13.1",
    "firebase-functions": "^2.0.2",
    "dialogflow": "^0.6.0",
    "dialogflow-fulfillment": "^0.6.1",
    "twilio": "^3.29.2",
    "nodemailer": "^4.7.0"
  }
}

However it is returning the following Fullfilment status

Webhook call failed. Error: DEADLINE_EXCEEDED, State: URL_TIMEOUT, Reason: TIMEOUT_WEB.

Deploy is working with no errors.

Could someone help me to find where my mistake is?

The function needs to return something in order to complete the webhook call. See the documentation on what would classify as an ok response
