It worked, and also I can add "token" . It seems like the "plugin" issue.

frps.ini 中的 plugin 相关配置注释掉，因为你没有启动插件，所以 frps 连接不到插件，就报错了。

#[plugin.user-manager]
#addr = 127.0.0.1:9000
#path = /handler
#ops = Login

#[plugin.port-manager]
#addr = 127.0.0.1:9001
#path = /handler
#ops = NewProxy

Thanks to @khs1994 , comment it and it worked.
Might add plugin configuration comment before [plugin.user-manager], or comment it as default.
For user first use might be more kindly.

@MicyToy Follow the document, not the full example configure file.
