List of Entrants not being passed from springboot to react

Question

I have a Tournament and TournamentEntrant Entity. When a member enters a tournament a new TournamentEntrant is created which consists of a Tournament, Member and score

public class TournamentEntrant {

    @Id
    @ManyToOne
    @JoinColumn(name = "member_id", referencedColumnName = "id")
    private Member member;

    @Id
    @ManyToOne
    @JoinColumn(name = "tournament_id", referencedColumnName = "id")
    private Tournament tournament;

    @Column(name = "totalScore")
    private double totalScore;

    public TournamentEntrant() {
    }

    public TournamentEntrant(Member member, Tournament tournament, double totalScore) {
        this.member = member;
        this.tournament = tournament;
        this.totalScore = totalScore;
    }
}

In the service I am adding the new TournamentEntrant to the list of TournamentEntrant in a Tournament

//Add the current entrant to the list of entrants for this event.
//en being a new TournamentEntrant
entrants.add(en);
t.setTournamentEntrants(entrants);
tournamentEntrantRepo.save(en);
tournamentRepo.save(t);

but when I get a Page of Tournament objects, the TournamentEntrant list isn't returned? I get all the other properties for a tournament.

The TournamentEntrant are there, if I get a Tournament from the db and then get the list of TournamentEnteant and print tournamentEntrant.getmember().getFirstName()` to console in spring, I get the name of the entrant.

I cant understand why they are not being returned to react when I get a Page of Tournaments
