Getting error when viewing username/profile.

Works OK when starting node app.js. But when I add the username to the URL, I get an error.

This is the error

Server running at http://<workspace-url>/

If I recall, one of the usernames that was listed in the video wasn't valid anymore, which would return a 404 (not found) if you tried to browse to it. However, this one is valid: http://teamtreehouse.com/chalkers.json so make sure that one is working for you first, then try to pick a few more to add to the list (try them in a browser first to make sure).

This is the route for username (excluding module.exports...etc):

// handle http route  get /: username i.e. /chalkers
function user(request, response){
  //if url == "/..." 
  var username = request.url.replace("/", "");
  if(username.length > 0) {
    response.writeHead (200, {'Content-Type': 'text/plain'});
    response.write("Header\n");

    // get json from Treehouse
       var studentProfile = new Profile(username);
      // on end
      studentProfile.on("end", function(profileJSON){
      // show profile      

      // store the values which we need
        var values = {
          avatarURL: profileJSON.gravatar_url,
          username: profileJSON.profile_name,
          badges: profileJSON.badges.length,
          javascriptPoints: profileJSON.points.JavaScript 
        }
        //simple response
         response.write(values.username + " has " + values.badges + " badges\n");
         response.end("Footer\n");
      });

      // on error    
      studentProfile.on("error", function(error){
      //show error   
      response.end("Footer\n");
    });

  }
}

I'm searching for my own profile, so it's not an issue of using a username that doesn't exist. Sorry for the updates, the formatting was crazy.

I think the error lies in "request.url.replace("/", ""); "

I'd console.log(username) after you define it to make sure it's coming out as you expect. It looks like it's coming out as "https.STATUS_CODES[response."... (the message cuts off)

Line 23 of profiles.js is what is throwing the error, I think it's probably expecting a username, but is being fed an error instead.

Hi James, yes, that seems to be the issue, but I can't figure out what's wrong. I'll keep investigating, I guess....

Edit: No, that is not the issue.

Also, FYI - your answers are going in the comments. Can't get credit for best answer in Comments and cant' get upvotes.
