当我将生成的Android客户端Java库与Google App Engine结合使用时，我得到了一个莫名其妙的500内部错误。基本上，我收到了一个500内部服务器错误，它从未显示在Google App Engine控制台的日志中。
这是我的堆栈跟踪：

有没有办法在Google App Engine控制台中找到未记录的内部错误？
当我将列表附加到我的请求时，似乎发生了错误。如：
SyncStuffRequest syncStuff = service.sync().syncStuff();
syncStuff .set("stuff", an ArrayList of StuffObjects);
syncResponse = syncStuff .execute();
