Heroku Deployment Application Error

I'm trying to deploy an API I wrote with Express and Node. I've tried deploying it both by connecting to Github and by using Heroku Toolbelt. Doing it both ways it says in the logs the app has deployed successfully but I go to the page and it always says:

Application Error

An error occurred in the application and your page could not be served. Please try again in a few moments.

If you are the application owner, check your logs for details.

I've made a Procfile with web: node index.js

Here's the code in my package.json and index.js files:

package.json:

{
  "name": "timestamp-microservice",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "edward-hong",
  "repository": {
    "type": "git",
    "url": "https://github.com/edward-hong/timestamp-microservice.git"
  },
  "license": "ISC",
  "engines": {
    "node": "4.4.0"
  },
  "scripts": {
    "start": "node index.js"
  },
  "dependencies": {
    "body-parser": "^1.15.1",
    "express": "^4.13.4",
    "moment": "^2.13.0"
  }
}

index.js:

var express = require('express');
var bodyParser = require('body-parser');
var moment = require('moment');
var port = process.env.PORT || 3000;
var app = express();
var timeRouter = express.Router();
timeRouter.use(bodyParser.json());
timeRouter.route('/:time')
  .get(function(req, res, next){
    var time = req.params.time;
    var unixTime = Number(time);
    if (unixTime){
      res.json({'unix': unixTime, 'natural': moment.unix(unixTime).format('MMMM D, YYYY')});
    } else {
      if (moment(time).isValid()){
        res.json({'unix': Number(moment(time).format('X')), 'natural': moment(time).format('MMMM D, YYYY')});
      } else {
        res.json({'unix': null, 'natural': null});
      }
    }
  });
app.use('/', timeRouter);
app.use(express.static(__dirname, 'index.html'));
app.listen(port, function(){
  console.log('Server running at http://oursite:' + port);
});

Here are the logs:

I was wondering how do I get it successfully deployed onto Heroku?

static middleware take two arguments, a string which is the root path of the directory to serve, and an option object.

For example

serveStatic('public/ftp', {'index': ['default.html', 'default.htm']})

In your case the second argument is a string, which is not correct.
