Generic Generator in hibernate to generate a UUID

Question

I am using HIBERNATE version: 5.6.15.Final, to try to generate a UUID when creating a relational table, I have the following definition of class attributes:

@Entity
@Table(name = "Regiones")
public class Region implements Serializable {
    private static final long SerialVersionUID = 1L;

    @Id
    @GeneratedValue(generator = "UUID")
    @GenericGenerator(
      name = "UUID", 
      strategy = "org.hibernate.id.UUIDGenerator"
    )
    @Getter
    @Setter
    private UUID Id;
}

But I get a runtime error: java.sql.SQLException: Field 'id' doesn't have a default value and the program stops. Is the strategy path defined in the GenericGenerator different for this version of hibernate? Or am I wrong about something else?
