var app = express();

// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'hjs');

// port setup
app.set('port', process.env.PORT || 3000);

// uncomment after placing your favicon in /public
//app.use(favicon(__dirname + '/public/favicon.ico'));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));

    err.status = 404;
    next(err);

// error handlers

// development error handler

            message: err.message,
            error: err
        });

// no stacktraces leaked to user
app.use(function(err, req, res, next) {

[update.js]

/* GET users listing. */
router.get('/', function(req, res, next){
	global.User.findOneAndUpdate({userName: req.query.userName},

		function(err, doc){
			if(doc != null)
				res.send("success!");
			else
				res.send("fail");
		});
});

module.exports = router;

Another Try: Input userName that does not exist by intention.
