Hello, I've been looking at this <https://github.com/typesense/typesense/issues/1985|issue> 'Inconsistent import behavior for nested fields with `null` value' for a while now and have gotten around to attempting to reproduce the bug within the <https://github.com/typesense/typesense/blob/v29/test/collection_nested_fields_test.cpphttps://github.com/typesense/typesense/blob/v29/test/collection_nested_fields_test.cpp|collection_nested_fields_test.cpp> file (typesense/test/collection_nested_fields_test.cpp). Specifically within this unit test 'CollectionNestedFieldsTest.UpsertWithNullValueOnOptionalField' I have pasted in this repro code provided in the issue:

```{
    "id": 1,
    "name": null,
    "address": {
      "city": "Freetown",
      "country": null
    }
}```
After testing this input, as well as many other inputs with null values in nested fields, it returned 'pass' indicating no error? By chance has this issue already been solved? If not, I would appreciate any pointers and guidance towards completing this first contribution of mine.
