Java 谷歌应用程序引擎中没有代码500内部错误的日志

当我将生成的android客户端java库与Google App Engine结合使用时，我遇到了一个无法解释的500内部错误。基本上，我得到了一个500内部服务器错误，它从来没有出现在谷歌应用程序引擎控制台的日志中

这是我的stacktrace：

有没有办法在谷歌应用程序引擎控制台中找到未标记的内部错误

当我将列表附加到请求时，似乎会发生此错误。例如：

SyncStuffRequest syncStuff = service.sync().syncStuff();

syncStuff .set("stuff", an ArrayList of StuffObjects);

syncResponse = syncStuff .execute();

您是否已在服务代码中放入任何日志语句，并检查它们是否出现在控制台中。您还可以在logging.properties中增加日志级别以进行调试，并查看控制台中是否出现问题。最大的问题是我得到了一个响应代码，但方法调用从未在控制台中注册
