Unable to get errors on my page (Reading from files - Node)

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

    render.construct("header",{},response);
    render.construct("search",{},response);
    render.construct("footer",{},response);
    response.end();
  }
  //if url == "/" && POST
    //redirect to /:username
}

//Handle HTTP route GET /:username i.e. /chalkers
function user(request, response) {

I notice that every other time you call render.construct() you use three arguments, with the third being response. When you call it for the error template, it only has two.
