Error: ENOENT: no such file or directory... when requesting URL.

Well, I gave it a good go but I suspect there's some sort of breaking change in the code as it;s been quite a while since the course was released. From what I gather I need to find a way to get the string representation of the URL for the templates but all I keep getting back is an object. [object Object]

I've tried stringify and .toString but I only get the same error back. Any more ideas? Thanks

router.js
var Profile = require("./profile.js");
var Render = require("./render.js")

function home(request, response) {
    if(request.url === "/") {
        response.writeHead(200, {"content-type":"text/plain"});
        Render.view("header", {}, response);
        Render.view("search", {}, response);
        Render.view("footer", {}, response);
        response.end();
    }
}

function user(request, response) {
    var username = request.url.replace("/","")
    if(username.length > 0) {

        response.writeHead(200, {"content-type":"text/plain"});
        Render.view("header", {}, response);

        //get json from Treehouse API
        var studentProfile = new Profile(username);

        studentProfile.on("end", function(profileJSON){
            //show profile

            //store the values which we need

            var values = {
                avatarUrl: stringify(profileJSON.gravatar_url),
                username: stringify(profileJSON.profile_name),
                badges: stringify(profileJSON.badges.length),
                javascriptPoints: stringify(profileJSON.points.JavaScript),
            }

            //simple response
            response.write("The user " + values.username + " has " + values.badges + " Treehouse badges!" + "\n");
            Render.view("profile", {values}, response);
            Render.view("footer", {}, response );
            response.end();



        });        

        studentProfile.on("error", function(error){
            //on error
            Render.view({errorMessage: error.message} + "\n");
            Render.view("footer", {}, response);
            response.end();
        });

    }

}

module.exports.user = user;

var fs = require("fs");

function mergeValues(values, content) {
    //Cycle over the keys
      //Replace all {{key}} with the value from the values object.
    for(let key in values) {
        content = content.toString().replace("{{" + key + "}}", values[key]);
    }
    //return merge content
    return content;
}

function view(templateName, values, response) {
    //read from the template file


    var fileContents = fs.readFileSync("./views/" + templateName + ".html", {encoding: "utf8"});
    fileContents = mergeValues(values, fileContents);

Hi there! I'm sorry, I haven't been able to. I had a quick dip back in and tried to edit for the first string in the directory for the readFilesync() method. It also doesn't like something about the header.html but I don't know what at the moment!
