http localhost 5000 tasks出现500错误

Question

系统win10 ，装了anaconda3环境 用的是python3 pyspider0.3.7
webui点击recent active tasks显示

Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

然后命令行显示如下错误，求助，非常感谢！
