dialogflow connection to firebase error: Webhook call failed. Error: Request timeout

Question

Dialogflow agent via cloud functions inline editor gives the following error: "Webhook call failed. Error: Request timeout." When trigetting a cloud function "handleReadTemp"

Cannot observe any other errors, tested the intent itself and it works on other basic/non-firebase related responses.

Inline editor cloud function code;

'use strict';

const functions = require('firebase-functions');
const admin = require("firebase-admin");
const {WebhookClient} = require('dialogflow-fulfillment');
const {Card, Suggestion} = require('dialogflow-fulfillment');

admin.initializeApp({
  credential: admin.credential.applicationDefault(),
  databaseURL: 'ws://urlFromFirebase.firebaseio.com/'
});  

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));

  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?`);
  }
  function handleReadTemp(agent) {
    return admin.database().ref('dev/data/012dsf/').limitToLast(1).once('value').then((snapshot) => {
    const value = snapshot.child('Temp').val();
     agent.add(`The temperature right now is`); 
    });
  }
  let intentMap = new Map();
  intentMap.set('Default Welcome Intent', welcome);
  intentMap.set('Default Fallback Intent', fallback);
  intentMap.set('temperatureStatus', handleReadTemp);
  agent.handleRequest(intentMap);
});

Webhook call failed. Error: Request timeout.

Any direction would be appreciated.

And change the way you initialize your app. First off: [the database URL shold be a HTTP address](https://firebase.google.com/docs/admin/setup#initialize_the_sdk). Secondly, you can call `.initializeApp()` without any parameters if you are just using default project. — Dennis Alund, Mar 28 '19 at 13:53
agc, your fulfillment URL should be the URL of your HTTP cloud function. It should look something like this: `https://us-central1-YOURPROJECT-ID.cloudfunctions.net/dialogflowFirebaseFulfillment` — Dennis Alund, Mar 28 '19 at 13:56
@DennisAlund I can see few of my other functions created manually through Firebase, however cannot see the one related to dialogflow project. I am signed-in under the same account, am I missing some configuration between the two? — agc, Mar 28 '19 at 14:02
Hard to tell. Too many unknowns. If you want the full answer to that, then your question need to provide screenshots of your Dialogflow configuration, full logs of your `firebase deploy` output and anything else that might help. — Dennis Alund, Mar 28 '19 at 14:08
@DennisAlund I think I got it now, since it wasn't showing under my account, it meant that I didn't select the project for the agent which was the case. Now connects successfully though getting a "null" result for the value. function: ````function handleReadTemp(agent) { return admin.database().ref('avr-iot/data/01234245A3E58A0BFE/').limitToLast(1).once('value').then((snapshot) => { const value = snapshot.child('Temp').val(); agent.add(`The temperature right now is ${value}`); }); }```` and the DB structure is: [link] https://imgur.com/Tg89Gxr — agc, Mar 28 '19 at 14:16
