App Engine Bulk Loader問題

我正在嘗試創建批量加載程序以將數據上傳到數據存儲區。但是，當我嘗試上傳它時，我面臨着這個錯誤和堆棧跟蹤：App Engine Bulk Loader問題

有沒有人有一些建議？

我相信它在將CSV轉換爲布爾值時會掛起。如果該字段爲真，則該字段具有「y」，否則沒有。但是，我找不到有關transform.regexp_bool的文檔。

除非您向我們展示導致問題的代碼 - 在本例中爲yaml文件 - ，否則我們無法提供幫助。 – 2010-09-20 09:26:11

我其實已經想通了 - 這些字段的名稱區分大小寫！這個非常重要。他們必須明確地匹配csv文件！
