How to make a Onetoone in JPA with composite primary key?

Question

How to put a User inside Serveruser?

I tried it like this. It creates the database, but it keeps throwing me an exception

And also he is creating a new user_idd field, would like to use the user_id of the composite primary key

WARN 11548 --- [ main] o.h.t.s.i.ExceptionHandlerLoggedImpl : GenerationTarget encountered exception accepting command : Error executing DDL "alter table server_user drop foreign key FKfcgk1es5us7bqb3o868xoawm7" via JDBC Statement

spring.jpa.hibernate.ddl-auto=create-drop
spring.datasource.url=jdbc:mysql://localhost:3306/blush
spring.datasource.username=root
spring.datasource.password=12345678
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect

public class User implements Serializable {
    @Id
    private Long id;
    
    // ... outras propriedades
    // ... contrutores, getters e setters
}

public class ServerUser implements Serializable {
    @EmbeddedId
    private ServerUserID id;
    
    @OneToOne(cascade = CascadeType.ALL, optional = false)
    @JoinColumn(name = "user_idd", referencedColumnName = "id")
    private User user;
    
    // ... outras propriedades
    // ... contrutores, getters e setters
}
