JPA Bidirectional Link - Infinite Loop / Circular Link

I have bi-directional communication

@Entity
@Table(name = "facility")
public class Facility implements Serializable {

    @Id
    @GeneratedValue
    private Long id;

    @OneToMany(mappedBy = "facility")
    private Set<Amenity> amenities;
}

@Entity
@Table(name = "amenity")
public class Amenity  implements Serializable {
    @Id
    @GeneratedValue
    private Long id;

    @ManyToOne
    private Facility facility;
}

      

        
        
        
      

    

Everything works fine and I can see that the table has been created correctly. I can add data to the rest endpoint, but that was only when I wanted to go the opposite direction and get a convenience facility when I had this problem. It looks like it goes into an infinite loop, the object calls amenity calls a convenience call and so on. It looks like a circular link. I have searched high and low, far and wide and followed many examples and all seem to have objects created in a similar way. I have left getters and setters for brevity. I expect that after it gets its first convenience it will stop.

        "id": 1,

        "facilityCode": "asdf",
        "amenities": [
            {

                    "id": 1,
