Java Local Development Environments Advanced Tooling Finishing TreeStory

Looks like you didn't present the TreeStory(3).

Hello All,

I completed my code and it runs via IntelliJ. I even see the output if I "preview" my code but the challenge is still telling me I didn't present the TreeStory. I am assuming the 3 refers to the third pseudo-test which says to present the finished story to the user. But the preview of the output even shows "Here is your complete story: ##story the test created##" So I'm not sure where I've gone wrong. Any help would be appreciated!

Main.java

package com.teamtreehouse;

import java.io.IOException;

public class Main {

    public static void main(String[] args) {

        Prompter prompter = new Prompter();
        System.out.println("Write a fun story! Create a fill in the blank story with two underscores on each side of the variable like __noun__ or __adjective__!");
        String userInput = null;
        String defaultStory = "Thanks __name__ for helping me out. You are really a __adjective__ __noun__ and I owe you a __noun__.";
        try {
            userInput = prompter.promptForStory();
        } catch (IOException e) {
            e.printStackTrace();
        }

        if (userInput.contains("__")) {
            Template userTemplate = new Template(userInput);
            prompter.run(userTemplate);
        } else {
            Template defaultTemplate = new Template(defaultStory);
            prompter.run(defaultTemplate);
        }
    }
}

        return words;
    }

    /**

    public String promptForWord(String phrase) throws IOException {

        String response = mReader.readLine();
            while(mCensoredWords.contains(response.toLowerCase().trim())) {
                System.out.printf("That word isn't very nice. Please enter a new word for %s. %n%n", phrase);
                response = mReader.readLine();
            }
            String enteredWord = response.toLowerCase().trim();

        return enteredWord;
    }
}

What I see when I run the preview in the code challenge

Write a fun story! Create a fill in the blank story with two underscores on each side of the variable like __noun__ or __adjective__!
Please enter a first prompt. 
Please enter a second prompt. 
That word isn't very nice. Please enter a new word for second prompt. 

That word isn't very nice. Please enter a new word for second prompt.

I figured out my problem... I was returning the prompt for word as lowercase. The challenge checker thing didn't like that. I changed the return in my promptForWord method to return response.trim(); instead of return response.toLowerCase().trim(); and that resolved it. Frustrating that the description of the "error" couldn't be more helpful.
