Spring JPA Parameter value [1000] did not match expected type [ma.mycom.myapp.domain.Client (n/a)]

Question

I have two entities called Appointement and Client, and I would like to get all the appointements of a given client. I am struggling with the following error message when I try to do so.

2022-05-24 13:30:41.685 WARN 23252 --- [ XNIO-3 task-1] .m.m.a.ExceptionHandlerExceptionResolver : Resolved [org.springframework.dao.InvalidDataAccessApiUsageException: Parameter value [1000] did not match expected type [ma.mycom.myapp.domain.Client (n/a)]; nested exception is java.lang.IllegalArgumentException: Parameter value [1000] did not match expected type [ma.mycom.myapp.domain.Client (n/a)]]

Here are my entities:

Client.java

@Entity
@Table(name = "CLIENTS")
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class Client implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "sequenceGenerator")
    @SequenceGenerator(name = "sequenceGenerator")
    @Column(name = "id")
    private Long id;

    //other attributes, getters, setters
    
}

Appointment.java

@Entity
@Table(name = "APPOINTMRNTS")
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class Appointment implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "sequenceGenerator")
    @SequenceGenerator(name = "sequenceGenerator")
    @Column(name = "id")
    private Long id;
    //other attributes

    @ManyToOne
    @JoinColumn(name = "ID_CLIENT")
    private Client client;

   //getters, setters
    
}

Controller, and how I call the query:

List<Appointement> clientAppointements = appointementRepository.findAllByClient(idClient);

Here is the query used in AppointementRepository.java (I guess it's the source of the problem)

@Query(
        name = "SELECT pe.* FROM APPOINTEMENTS pe INNER JOIN CLIENTS e ON pe.ID_CLIENT = e.ID WHERE e.id = ?1",
        nativeQuery = true
    )
List<Appointement> findAllByClient(Long idClient);
