Google API Python客戶端（http://code.google.com/p/google-api-python-client/）有一個示例應用程序，演示了Google App Engine基礎結構上的OAUTH2。這可以在這裏找到：Google API Python客戶端OAUTH Appengine示例borked？

我試圖抓住這個例子中，在我的應用程序的憑據的client_secrets.json填充，但與當地dev_appserver運行我得到：

當我部署應用程序使用appcfg.py住在GAE上，當我前往我的應用程序的根頁面，我得到一個500服務器錯誤，並發展控制檯日誌閱讀：

那麼，呃，幫忙？
FWIW，我也跟着在整個客戶端代碼複製到應用程序引擎項目（截至http://code.google.com/p/google-api-python-client/wiki/GoogleAppEngine概述）的說明
