Azure MobileServices TableControllerにアクセス中にサーバーエラーが発生しました

Question

Azure Mobile Appテンプレートを使用して、TableController APIを作成し、アズールに展開しました。

私はURLからテストし、私は

http://rkXXXXXXXXXXX.azurewebsites.net/tables/Person/f90cb37d51a34f8cb97432a57000c876?ZUMO-API-VERSION=2.0.0 

以下のURLを使用する場合、それは正常に動作しています今、私はXamarinは、それを消費するアプリを形成し、私がログに内部サーバーエラーを受けています作成し、それを使用することはできません。私は、サーバーアプリケーションを複数回展開してみました

Answer 1

モデルオブジェクトのデータ型の不一致が原因で問題が発生しました。私はdatetimeオブジェクトをデータベース内にdatetimeoffsetと定義し、DTOオブジェクトにはdatetimeと定義しています。私のDTOオブジェクトのデータ型を変更した後、正常に動作しました。
