What is the meaning of this error message? I get this message when
updating "Tenant"

Attempt was made to manually set the id component of a Key primary
key.  If you want to control the value of the primary key, set the
name component instead.

this is my entity class

@Entity
public class Tenant {

        @Version()
        private Long version;
        @Id
        @GeneratedValue(strategy = GenerationType.IDENTITY)
        private Long tenantId;

        @OneToOne(cascade=CascadeType.ALL)
        private Contact contact;
.....
}


@Entity
public class Contact {

        @Version
        private Long version;
        @Id
        @GeneratedValue(strategy = GenerationType.IDENTITY)
        private Key contactId;

....
}
