JavaScript Build a Simple Dynamic Site with Node.js Handling Routes in Node.js Handling Routes Review

There was a communication problem


When trying to check my work in the Node JS quiz, I got the following error: There was a communication problem.

What should I do?

Thank you, Best regards

function root(request, response) {
    if(request.url == "/") {
        response.writeHead(200, {'Content-type': "text/plain"});

function contact(request, response) {
    if(request.url == "/contact") {
        response.writeHead(200, {'Content-type': "text/plain"});

function about(request, response) {
    if(request.url == "/about") {
        response.writeHead(200, {'Content-type': "text/plain"});

module.exports.root = root;
module.exports.contact = contact;
module.exports.about = about;
var http = require("http");
var routes = require("./routes.js");

http.createServer(function(request, response){
    routes.root(request, response);
    routes.contact(request, response);
    routes.about(request, response);

It sounds like just a problem with the quiz engine rather than something you've done. Try again in a few minutes.

You may have to contact Treehouse support to let them know if it keeps happening. :-)
