Simple cloud function to get database data is not working.

getusermessage() is not working

Error:

Function execution took 60002 ms, finished with status: 'timeout'

Index.JS for getting database result.

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
const cors = require('cors')({origin: true});

// Take the text parameter passed to this HTTP endpoint and insert it into the
// Realtime Database under the path /messages/:pushId/original
exports.addMessage = functions.https.onRequest((req, res) => {
  // Grab the text parameter.
  const original = req.query.text;
  // Push the new message into the Realtime Database using the Firebase Admin SDK.
  admin.database().ref('/messages').push({original: original}).then(snapshot => {
    // Redirect with 303 SEE OTHER to the URL of the pushed object in the Firebase console.
    res.redirect(303, snapshot.ref);
  });
});

// Listens for new messages added to /messages/:pushId/original and creates an
// uppercase version of the message to /messages/:pushId/uppercase
exports.makeUppercase = functions.database.ref('/messages/{pushId}/original')
    .onWrite(event => {
      // Grab the current value of what was written to the Realtime Database.
      const original = event.data.val();
      console.log('Uppercasing', event.params.pushId, original);
      const uppercase = original.toUpperCase();
      // You must return a Promise when performing asynchronous tasks inside a Functions such as
      // writing to the Firebase Realtime Database.
      // Setting an "uppercase" sibling in the Realtime Database returns a Promise.
      return event.data.ref.parent.child('uppercase').set(uppercase);
    });

var db = admin.database();
exports.getUserMessage = functions.https.onRequest((req, res) => {
var query = db.ref("messages").orderByKey();
query.once("value")
  .then(function(snapshot) {
    snapshot.forEach(function(childSnapshot) {
      var key = childSnapshot.key;
      // childData will be the actual contents of the child
      var childData = childSnapshot.val();
  });
});  
});

What am O doing wrong?

You didn't say which of your three functions is timing out, but I'll take a guess at which one. Your HTTPS function getUserMessage isn't generating a response to the client. Cloud Functions will wait for 60 seconds (by default) for it to generate a response, and if it doesn't, it will kill the function and leave that message in the log.

Every code path in an HTTPS function should generate some response to the client.

You can set the timeout and memory using runWith during function declaration,

exports.getUserMessage = functions.runWith({ memory: '2GB', timeoutSeconds: 360 }).https.onRequest(
