Portal 报错 Internal Server Error

[jimmyLin]

您好，我在使用portal时候，./control start 之后，访问

127.0.0.1:5050

出现internal service error
查看日志信息如下：

我在portal中的配置如下：

UIC_ADDRESS = {
    'internal': 'http://127.0.0.1:1234',
    'external': 'http://127.0.0.1:1234',
}

我也尝试了将external配置成内网ip：192.168.3.181，并且访问192.168.3.181:5050，还是出现一样的错误。
fe监听的端口地址是 0.0.0.0:1234

我不知道问题出在哪里，有人能解答吗？
