我正在使用 Node v4.4.0、npm 2.14.20 和sails 0.10.5。我已经使用 Google OAuth2 创建了简单的应用程序（我所拥有的只是具有用户模型的 Auth 控制器并在 config/passport.js 中配置了护照），它在本地运行时工作正常，但在 Heroku 上部署时失败。从日志中，我怀疑在用户已经通过 Google 身份验证后创建新会话存在问题。我在下面附加了一个日志，以前有人遇到过类似的问题吗？

当您将某个对象分配给该对象的某个键时，会发生循环结构错误。例如...

var obj={
  'x':1,
  'y':false
};
obj.z=obj;//or anyhow this happens by mistake

看截图！！！

所以这是形成了圆形对象......并且在对这些对象进行字符串化时会导致异常。
