Java Intro to Java Web Development with Spark Diving into Web Development Introduction

Is something wrong with my code because it doesn't work the way I want it to.

The version of IntelliJ Craig and I are using is completely different so when I made my project it had a different formatting than the one Craig has so it makes this kinda hard to do

This is Main.java

package com.teamtreehouse.courses;

public class Main {
    public static void main(String[] args) {
         get("/hello", (req, res) -> "Hello World");

         get("/", (req, res) -> {
             return new ModelAndView(null,"index.hbs"
         }, new HandlebarsTemplateEngine());

this is Index.hbs

<!doctype html>
<html lang="en">
   <meta charset="UTF-8">
    <title>Hello Students</title>
    <h1>Welcome Students!</h1>
    <!--TODO:csd - Add sign in! -->
    <form action="/sign-in" method="post">
        <input type="text" placeholder="What's your user name?" name="username">
    <button>Sign in</button>
