将对象复制到Realm时出错

Question

我正在尝试更新RealmObject，但我一直收到以下错误日志：

Cannot copy an object from another Realm instance.

java.lang.IllegalArgumentException: Cannot copy an object from another Realm instance.

更新对象的代码是：

realm.executeTransactionAsync(new Realm.Transaction() {
                @Override
                public void execute(Realm realm) {
                    Favorite favorite = realm.where(Favorite.class).findFirst();

                    favorite.getTracks().add(getCurrentTrack());
                    realm.copyToRealmOrUpdate(favorite);
                }
            }, new Realm.Transaction.OnSuccess() {
                @Override
                public void onSuccess() {
                    Toast.makeText(AudioPlayer.this, "Added to favorites", Toast.LENGTH_SHORT)
                            .show();
                }
            }, new Realm.Transaction.OnError() {
                @Override
                public void onError(Throwable error) {
                    Log.e(TAG, error.getMessage(), error);
                }
            });
