Столбец не может быть нулевым во многих отношениях при добавлении

У меня есть 2 таблицы Products и Entrepot (Warehouse), и они имеют много-много отношений.Когда я пытаюсь добавить новый продукт в массив entrepotProducts и сохранить экземпляр entropot, я получаю, что product_id не может быть нулевым

Enrepot.java 

@Entity(name= "Entrepot")
@Table(name = "entrepot")
@Data
@ToString(exclude = "EntrepotProduct")
@EqualsAndHashCode(exclude = "entrepotProduct")
@RequiredArgsConstructor
@NoArgsConstructor
public class Entrepot {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;


private @NonNull String name;


private @NonNull String address;


private @NonNull Integer capacite;

private boolean etat;

@OneToMany(
        mappedBy = "entrepot",
        cascade = CascadeType.ALL,
        orphanRemoval = true
)
private List<EntrepotProduct> entrepotProducts= new ArrayList<>();

@Column(nullable = false, updatable = false)
@CreationTimestamp
private Date createdAt;

public void removeProduct(Product p) {
    for (Iterator<EntrepotProduct> iterator = entrepotProducts.iterator();
         iterator.hasNext(); ) {
        EntrepotProduct ep = iterator.next();

        if (ep.getEntrepot().equals(this) && ep.getProduct().equals(p)) {
            iterator.remove();
            ep.getProduct().getEntrepotProducts().remove(ep);
            ep.setEntrepot(null);
            ep.setProduct(null);
        }
    }
}

Product.java 

@Entity(name= "Product")
@Table(name = "product")
@Data
@ToString(exclude = "EntrepotProduct")
@EqualsAndHashCode(exclude = "entrepotProduct")
@RequiredArgsConstructor
@NoArgsConstructor
public class Product {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;


private @NonNull String name;

private @NonNull float volume;

private @NonNull int quantite;

private @NonNull float price;

@OneToMany(
        mappedBy = "product",
        cascade = CascadeType.ALL,
        orphanRemoval = true
)
private List<EntrepotProduct> entrepotProducts= new ArrayList<>();

@Column(nullable = false, updatable = false)
@CreationTimestamp
private Date createdAt;

}

EntrepotProduct.java 

@Entity

@Getter
@Setter
@NoArgsConstructor
@RequiredArgsConstructor
public class EntrepotProduct implements Serializable{

@Id
@ManyToOne
@JoinColumn(name = "product_id")
private Product product;

@Id
@ManyToOne
@JoinColumn(name = "entrepot_id")
private Entrepot entrepot;

private @NonNull Integer capacite;

@Override
public boolean equals(Object o) {
    if (this == o) return true;
    if (o == null || getClass() != o.getClass())
        return false;

    EntrepotProduct that = (EntrepotProduct) o;
    return Objects.equals(product.getId(), that.product.getId()) &&
           Objects.equals(entrepot.getId(), that.entrepot.getId());
}

@Override
public int hashCode() {
    return Objects.hash(product.getId(), entrepot.getId());
}
}

Контроллер:

ЭТОТ КОД РАБОТАЕТ: 

    Entrepot en1 = new Entrepot("E","Essaouira",100);
    entrepotRepository.save(en1);
    log.info(en1.toString());

    Entrepot en2 = new Entrepot("E","Jdida",777);
    entrepotRepository.save(en2);
    log.info(en2.toString());

    Product p = new Product("P100",987,22,777);
    p.getEntrepotProduct().add(new EntrepotProduct(p, en1, 888));
    p.getEntrepotProduct().add(new EntrepotProduct(p, en2, 666));
    productRepository.save(p);

ЭТО НЕ РАБОТАЕТ: 

    Entrepot en1 = entrepotRepository.findById(4).get();
    entrepotRepository.save(en1);
    log.info(en1.toString()); // it is not null

    Entrepot en2 = entrepotRepository.findById(7).get();
    entrepotRepository.save(en2);
    log.info(en2.toString()); // it is not null

    Product p = new Product("P100",987,22,777);
    p.getEntrepotProduct().add(new EntrepotProduct(p, en1, 888));
    p.getEntrepotProduct().add(new EntrepotProduct(p, en2, 666));
    productRepository.save(p);
