My own version does not display entities in the table

[madeofstardust]

Hi,
I tried to adjust the schema to my own classes, but the table on the localhost:8080 remains empty, and localhost:8080/api displays Whitelabel Error Page.

My app.js:

'use strict';

// tag::vars[]
const React = require('react');
const ReactDOM = require('react-dom');
const client = require('./client');
// end::vars[]

// tag::app[]
class App extends React.Component {

	constructor(props) {
		super(props);
		this.state = {all_stories: []};
	}

	componentDidMount() {
		client({method: 'GET', path: '/api/all_stories'}).done(response => {
			this.setState({all_stories: response.entity._embedded.all_stories});
		});
	}

	render() {
		return (
			<All_StoriesList all_stories={this.state.all_stories}/>
		)
	}
}
// end::app[]

// tag::employee-list[]
class All_StoriesList extends React.Component{
	render() {
		const all_stories = this.props.all_stories.map(all_story =>
			<All_Story key={all_story._links.self.href} all_story={all_story}/>
		);
		return (
			<table>
				<tbody>
					<tr>
						<th>Title:</th>
						<th>ID:</th>
					</tr>
					{all_stories}
				</tbody>
			</table>
		)
	}
}
// end::employee-list[]

// tag::employee[]
class All_Story extends React.Component{
	render() {
		return (
			<tr>
				<td>{this.props.all_story.title_of_a_story}</td>
				<td>{this.props.all_story.ID}</td>
			</tr>
		)
	}
}
// end::employee[]

// tag::render[]
ReactDOM.render(
	<App />,
	document.getElementById('react')
)
// end::render[]

My All_stories class:

package com.greglturnquist.payroll;
import javax.persistence.*;
import java.util.List;
import java.util.Objects;

@Entity
@Table(name = "All_stories"

)

public class All_stories {

    @Column(name = "ID")
    private int ID;

    @Id
    @Column(name="Title_of_a_story")
    private String title_of_a_story;

    @OneToMany(mappedBy = "all_story")
    private List<Novel> novels;

    private All_stories(){}

    public All_stories(int ID, String title_of_a_story) {
        this.ID = ID;
        this.title_of_a_story = title_of_a_story;
    }


    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        All_stories all_story = (All_stories) o;
        return Objects.equals(ID, all_story.ID) &&
                Objects.equals(title_of_a_story, all_story.title_of_a_story);
    }

    @Override
    public int hashCode() {

        return Objects.hash(ID, title_of_a_story);
    }

    public int getID() {
        return ID;
    }

    public void setID(int ID) {
        this.ID = ID;
    }

    public String getTitle_of_a_story() {
        return title_of_a_story;
    }

    public void setTitle_of_a_story(String title_of_a_story) {
        this.title_of_a_story = title_of_a_story;
    }

    public List<Novel> getNovels() {
        return novels;
    }

    public void setNovels(List<Novel> novels) {
        this.novels = novels;
    }
}

Could You please give me a hint, what is wrong?
