当我尝试创建新的配置文件时，我的应用程序崩溃了。我的日志显示“客户端请求中断”错误。您可以在下面查看我的日志。
我在heroku开发中心搜索了此错误：https://devcenter.heroku.com/changelog-items/662
在此页面上（https://devcenter.heroku.com/changelog-items/662）：
它说：“如果客户端套接字在请求过程中或在返回响应之前关闭，则将记录此错误。”
然后
“此错误情况导致记录H18，并且可以使用袜子字段来区分现在是H18和H27错误。”
H18-服务器请求中断
在后端返回HTTP响应之前，关闭了属于您应用程序的Web进程的后端套接字。

需要注意的重要部分是sock = client，这意味着该请求已根据客户端的请求而中断：

我既不了解Heroku开发人员的说明，也不了解以前的Stack Overflow问题。
非常感谢您的回答。
