### Steps To Reproduce
Use this code:
https://gerogit.eu/eunify/backend/blob/master/src/eu/newsapp/backend/algolia/algolia.kt#L61-79

AlgoliaHttpClient.java と、Utils.parseAs を通じて参照される AlgoliaError のデシリアライゼーションパスから始め、続いて APIClient.java の addObject 呼び出しを追跡します。Issue に記載されたレスポンスを再現し、position フィールドを含むエラーがデシリアライゼーションの失敗なしに処理されることを確認します。
