500 Internal Error - Again

I've been following the video of Craig Dennis about Spark, and I've reached the part where we make out 'index.hbs' file and then alter our java code to call the file. however when I run it I get 500 internal error on the localhost and then I get this as one of the errors

One of the errors I get in the IntelliJ terminal is ''' [qtp645337405-21] INFO spark.http.matching.MatcherFilter - The requested route [/index] has not been mapped in Spark for Accept: [text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,/;q=0.8] '''

public class Main {
    public static void main(String[] args) {

        //Map map = new HashMap();
        //map.put("name", "Imtanan");
       // get("/", (rq, rs) -> new ModelAndView(map, "index.hbs"), new HandlebarsTemplateEngine());

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

Cool, move your index.hbs file into a new folder resources/templates/index.hbs.

Weird error, but looks like you missed creating that templates folder.

Hope this works!

Hmmm... are you going to http://localhost:4567/ or someplace else? Looks like you might be requesting the /index page, which you haven't mapped, you just mapped the /

I'm going exactly to that link Craig Dennis and it still shows the same error, despite me having rerun the server

I'm not sure it would matter, but can you tell me where the index.hbs file lives?

Also can you share your imports please? Only other thing I can think of ;)

yeah sure, my 'index.hbs' file resides C:\Users\Mani\IdeaProjects\course-ideas\src\main\resources\index.hbs and that is the direct path.

the imports are ::::

package com.teamtreehouse.courses;

import spark.ModelAndView; import spark.template.handlebars.HandlebarsTemplateEngine;

import static spark.Spark.get;

also I thought I'd add the dependencies as I had to add an extra to what the video showed as mine is a later version

compile 'com.sparkjava:spark-core:2.5.2'

compile 'com.sparkjava:spark-template-handlebars:2.3'

compile 'org.slf4j:slf4j-simple:1.7.21'

testCompile group: 'junit', name: 'junit', version: '4.11'

Thanks Craig Dennis :)
