Parse Objects not created from node in heroku - node.js

Question

I have the following code running on a node server # heroku. The trouble I am having is that the application frequently fails to create a new parse.com object on post. What is strange is that this code works 100% of the time on my local machine. running through heroku introduces the issue.
I run a heroku log trail when the application posts and it does not throw any exceptions/errors, so I'm stumped as to what to look for.
BTW - I realize this code isn't the prettiest, this is my first attempt to get a node/heroku/parse application up and running.
var http = require('http');
var url = require('url');
var path = require('path');
var fs = require('fs');
var Parse = require('parse/node').Parse;
var mime = require('mime');
var server = http.createServer(router).listen(process.env.PORT || 5000);
Parse.initialize("key", "key");
console.log("Parse initialized");
function router (req, res) {
var pathname = url.parse(req.url, true).pathname;
if (pathname.slice(0, 4) === '/api') {
apiHandler(req, res);
} else {
if (pathname[pathname.length - 1] === '/')
pathname += 'index.html';
staticFileHandler(pathname, res);
}
}
function staticFileHandler (pathname, res) {
fs.readFile(__dirname + '/public_html' + pathname, function (err, data) {
if (err) return errHandler(err, res);
console.log('[200]: ' + pathname);
res.setHeader('Content-Type', mime.lookup(path.extname(pathname)));
res.end(data);
});
}
function errHandler (err, res) {
if (err.code === 'ENOENT') {
res.statusCode = 404;
res.end('File not found!');
console.log('[404]: File not found: ' + err.path);
} else {
console.error(err);
}
}
function apiHandler (req, res) {
if (req.method === 'GET') {
//send back a list of todos
// var toDo = new Parse.Object("ToDo");
var parseQuery = new Parse.Query("ToDo");
parseQuery.find({
success: function(toDoList){
res.setHeader('Content-Type', mime.lookup('json'));
res.end(JSON.stringify(toDoList));
},
error: function(toDoList, error) {
// error is an instance of Parse.Error.
console.log('Error encountered while getting Parse objects: ' + error.message);
}
});
} else if (req.method === "POST"){
var body = "";
req.on('data', function (chunk) {
body += chunk;
});
var today = new Date();
req.on('end', function () {
var toDo = new Parse.Object("ToDo");
toDo.set('Description', body);
toDo.set('Done', false);
toDo.set('DueDate',today )
toDo.save(null, {
success: function(toDo) {
// Execute any logic that should take place after the object is saved.
console.log('New object created with objectId: ' + toDo.id);
},
error: function(toDo, error) {
// Execute any logic that should take place if the save fails.
// error is a Parse.Error with an error code and message.
console.log('Failed to create new object, with error code: ' + error.message);
}
});
});
res.end();
}
