 ### Fixed
 * Fixed an issue in `toJSON()`, in combination with primaryKeys, where data from another table could be returned. ([#3331](https://github.com/realm/realm-js/issues/3331), since v10.0.0)
-* Fixed an issue in `toJSON()` where `data` would output as `{}`, it now returns the data base64 encoded. ([#3356](https://github.com/realm/realm-js/pull/3356), since v10.0.0)
 * TS: `RealmInsertionModel<T>` used in `realm.create<T>(...)` now ignores functions on Class Models. ([#3421](https://github.com/realm/realm-js/pull/3421), since v10.0.0)
