Question

我的Web服务器上安装了Hangfire。而且有效。而且我能够访问hangfire仪表板。

但是今天突然间，我尝试打开仪表板，并尝试访问http://localhost/hangfire 我收到以下错误：

An unhandled exception occurred while processing the request.

由于仪表板是一些内部Hangfire工具-我只是在这里不知道如何解决此问题。由于SQL是由Hangfire安装的然后从nuget安装Hangfire。

有人遇到过这个问题吗？知道如何使hangfire仪表板出现吗？

谢谢。

对不起。

我刚刚意识到有人在一个hangfire表中重命名了[Key]列。一切正常。
