  <p>I am not sure what else to attach as code, but the booking entity looks like this:</p>
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>@Entity
  @Table(name = "bookings")
  public class BookingEntity extends BaseEntity {
  
      @Column(nullable = false)
      private Instant bookingTime;

      private LocalDate checkIn;
  
      @Column(nullable = false)
