Function execution took 60027 ms, finished with status: 'timeout' - firebase

Question

I have looked at several other timeout posts but nothing seems to help. I have a very basic setup going on here using a brand new functions project. In my logs I constantly see 'timeout'
Any ideas??
Here is the code
import * as functions from 'firebase-functions';
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
const express = require('express');
const cors = require('cors');
const app = express();
const bodyParser = require('body-parser');
exports.app = functions.https.onRequest(app);
app.use(cors({ origin: true }));
app.use(bodyParser.json()); // support json encoded bodies
app.use(bodyParser.urlencoded({ extended: true })); // support encoded bodies
app.use(cors);
app.get('/hello', (req, res) => {
res.status(200).send("Mateo");
});
Here is my package.json
{
"name": "functions",
"scripts": {
"lint": "tslint --project tsconfig.json",
"build": "tsc",
"serve": "npm run build && firebase serve --only functions",
"shell": "npm run build && firebase functions:shell",
"start": "npm run shell",
"deploy": "firebase deploy --only functions",
"logs": "firebase functions:log"
},
"main": "lib/index.js",
"dependencies": {
"body-parser": "^1.18.3",
"cors": "^2.8.5",
"express": "^4.16.4",
"firebase-admin": "^6.0.0",
"firebase-functions": "^2.1.0"
},
"devDependencies": {
"tslint": "~5.8.0",
"typescript": "~2.8.3"
},
"private": true
}
Here is how I execute my function

UPDATE
After making the changes suggested below I am still not having any luck. I'm not sure how much more bare bones it can get than this..
import * as functions from 'firebase-functions';
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
const express = require('express');
const app = express();
app.get('/hello', (req, res) => {
res.status(200).send("Mateo");
});
exports.app = functions.https.onRequest(app);
