spring data mongo No property b found on entity class when retrieving entity by Id

I have a parent class that has some shared fields and a child class that extends it.

@SuperBuilder(toBuilder = true)
@Data
public abstract class MultiTenantAuthoredDocument {

    @Indexed
    private String tenantId;

    @CreatedDate
    private LocalDateTime createdDate;

    @LastModifiedDate
    private LocalDateTime lastModifiedDate;
}


@Document(collection = "users")
@SuperBuilder(toBuilder = true)
@Data
@EqualsAndHashCode(callSuper = true)
@ToString(callSuper = true)
 public class User extends MultiTenantAuthoredDocument {

    @Id
    private String id;

    private String firstName;

    private String lastName;

    @Indexed
    private String password;

    @Indexed(unique = true)
    private String userName;

    @Indexed(unique = true)
    private String email;

    @Indexed
    private List<UserRole> roles;

    @Builder.Default
    private boolean enabled = false;

}

However when running my unit tests, I get an unexpected exception when I do a findById and there's a result found namely: No property b found on entity class be.moesmedia.erp.users.domain.User to bind constructor parameter to! As I have no clue where property b is coming from it's pretty difficult to see what I'm doing wrong.
If anyone can help me point out what I'm doing wrong.

So I've figured out what was going wrong, Lombok generated a constructor that accepted an Object with the properties for the SuperBuilder class. Once I added @NoArgsConstructorto both the child and parent class, it works like a charm.
