I have relation set between two classes

Nested class:

@Column(name = "owner_id", nullable = false)
  private UUID ownerId;
 
  @ManyToOne(fetch = FetchType.LAZY)
  @JoinColumn(name = "owner_id", nullable = false, insertable = false, updatable = false)
  private Owner owner;

Owner class:

@OneToMany(mappedBy = "owner",
      cascade = { CascadeType.PERSIST, CascadeType.REMOVE },
      fetch = FetchType.LAZY)
  private Set nestedSet;

In test I'm pre-persisting owner class in db, then set its id to nested entity and then store it with save repository method, when I'm calling nested.getOwner() on returned from the repository call entity, I have null. I tried to change

FetchType.LAZY to FetchType.EAGER

but it didn't work.
