python - Python BadValueError で Google App Engine に一括データをアップロードする

Question

約 1300 レコードで構成されるファイルをアップロードすると、エラーが発生します。問題は、どのレコードに問題があるのか​​、どのフィールドに問題があるのか​​さえわからないことです。appspot.com のログ画面でこれに関する情報が得られず、エラーからの出力が以下に示されます。手動でデータを分割せずに、どのレコードに問題があるかを特定する方法 (cvs ファイル) はありますか?

エラーログは次のとおりです。

リモート API を bulkloader.yaml で使用しています。
