UnityIAPのGooglePlayCSVが書き出せない

前提・実現したいこと

Unityで携帯アプリゲームを製作しています。
課金のシステムをUnityIAPのコードレスIAPを使用して導入しているのですが
GooglePlayに課金アイテム情報をインポートするためのCSVファイルが書き出せなくて困っています。

試したこと

IAP Catalog にはID、Type、Title、Description、Priceを設定済みでUDPも同期させて自動初期化のチェックも入れています。
Unity上で再生すると購入確認のウィンドウも表示されます(実機テストはできていません)。

しかし「AppStoreExport」の「GooglePlayCSV」をクリックして書き出そうとするとエラーが出てしまいます。

###エラーメッセージ
