SDK is failing to parse JSON object

According to below example we’ve this data structure in algolia, where some products have “key_features > en” but some don’t.

[
  {
    "key_features": {
      "en": [
        "lorem ipsum....",
      ]
    },
  }
]

When fetching below data in iOS SDK, while parsing it is throwing error somewhere here on this method - **try** $0.extractHits() : []

{
    "key_features": {},
}

If we add "en": [] key in above algolia data then it parses successfully.

ideally, no matter what- “en” key exist or not SDK should parse data successfully.

Can you please look into it and provide any solution for this issue?
