postgresql - Hibernate Spatial: Cannot construct instance of `org.locationtech.jts.geom.Geometry`

Question

I'm developing a routes app, to create, search or make routes in a city. This app has two different parts: a rest Service in Java, with a postgresql database and postgis, and a client app. The route that I'm creating has (among others) two fields called startCoordinates and endCoordinates which are of type Geometry (org.locationtech.jts.geom.Geometry, from Hibernate Spatial).

Here's the entity Route:

@Entity
@Table(name = "routes")
public class Route {

@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private long id;

@Column(name = "name")
private String name;

@Column(name = "description")
private String description;

@Column(name = "startPlace")
private String startPlace;

@Column(name = "startCoordinates", columnDefinition = "Geometry", nullable = true)
private Geometry startCoordinates;

@Column(name = "endPlace")
private String endPlace;

@Column(name = "endCoordinates", columnDefinition = "Geometry", nullable = true)
private Geometry endCoordinates;

@Column(name = "distance")
private Float distance;

The server starts with no problem, but when I use Postman to add a new route, I'm getting this error:
