Spring Boot Hibernate (book, authors) duplicate foreign key

Пытаюсь смоделировать предметную область с книгами и авторами. У меня получились такие доменные объекты:

Книга:

package aoizora.domain.book;

import aoizora.domain.author.Author;
import jakarta.persistence.*;
import lombok.Data;

import java.util.Set;

@Data
@Entity
public class Book
{
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long id;

    @Column
    private String title;

    @Column
    private String isbn;

    @ManyToMany
    @JoinTable(
            name = "book_authors",
            joinColumns = @JoinColumn(name = "book_id"),
            inverseJoinColumns = @JoinColumn(name = "author_id")
    )
    private Set<Author> authors;
}

Автор:

package aoizora.domain.author;

import aoizora.domain.book.Book;
import jakarta.persistence.*;
import lombok.Data;

import java.util.Set;

@Data
@Entity
public class Author
{
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long id;

    @Column
    private String firstName;

    @Column
    private String lastName;

    @ManyToMany(mappedBy = "authors")
    private Set<Book> books;
}

Конфиг приложения application.yml:

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/mysql
    username: root
    password: 123
    driver-class-name=com: com.mysql.jdbc.Driver
  jpa:
    hibernate:
      ddl-auto: update
    database-platform: org.hibernate.dialect.MySQL8Dialect
    defer-datasource-initialization: true
  sql:
    init:
      mode: always

При запуске всего этого возникает следующая ошибка:

org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL "alter table book_authors add constraint FKs4xm7q8i3uxvaiswj1c35nnxw foreign key (book_id) references book (id)" via JDBC [Duplicate foreign key constraint name 'FKs4xm7q8i3uxvaiswj1c35nnxw']

Почему она возникла? Как ее исправить?
