Code Challenge, finishing TreeStory

Question

Hello, I am having difficulties getting this to be accepted in the code challenge. IntelliJ Idea compiles and runs my code without errors. Meanwhile when I copy/paste the code to the code challenge I am getting a NullPointerException. I have went back and included an if statement just to check if the variable on the line specified are null or not in intelliJ.

Please give me some guidance for this. Please see bellow my code.

com/teamtreehouse/Main.java

package com.teamtreehouse;

import java.io.IOException;
import java.util.Arrays;
import java.util.List;

public class Main {

    public static void main(String[] args){
        // write your code here
        Prompter prompt = new Prompter();
        String story = prompt.promptForStory();
        Template tmpl = new Template(story);
        try {
            prompt.promptForWord(story);
        } catch (IOException e) {
            e.printStackTrace();
        }
        prompt.run(tmpl);
//        List<String> fakeResults = Arrays.asList(
//                "friend",
//                "talented",
//                "java programmer",
//                "high five");

#  This is essentially what I am testing 
1.  The user is prompted for a new string template (the one with the double underscores in it).

  a. The prompter class has a new method that prompts for the story template, and that method is called.

2.  The user is then prompted for each word that has been double underscored.

   a. The answer is checked to see if it is contained in the censored words.
      User is continually prompted until they enter a valid word

3.  The user is presented with the completed story
