Printing search results as a pdf using advanced html template

I think I am missing something as this code works without any errors, but the only thing the page contains is "render.TemplateRenderer". Any insight would be helpful

 /**

 * @NApiVersion 2.x

 * @NScriptType Suitelet

// This sample shows how to render search results into a PDF file.

define(['N/render', 'N/search', 'N/file'], function(render, search, file) {

  function onRequest(options) {

    var request = options.request;

    var response = options.response;

var SOsearch = search.load({

id: '2277' //'customsearchitem_label_print' //the ID of the saved search

});

var resultSet = SOsearch.run();

var results = resultSet.getRange(0, 10);

    //var results = SOsearch.getRange(0, 100);

     

//var xmlTemplateFile = file.load('Templates/PDF Templates/invoicePDFTemplate.xml'); //this will be the template file filepath
