问主路由器出口内部的二次路由器出口不能工作

EN

对于我的路由器，我有以下配置。次要路由器出口包含在主路由器中。当我尝试使用routerLink来显示roster.component.html时，它会抛出以下错误:我尝试了许多不同的配置，但我不明白为什么它不能工作。

错误错误：" object“resolvePromise http://localhost:4200/polyfills.js:3159:31 resolvePromise http://localhost:4200/polyfills.js:3116:17 scheduleResolveOrReject http://localhost:4200/polyfills.js:3218:17 invokeTask http://localhost:4200/polyfills.js:2766:17 onInvokeTask http://localhost:4200/vendor.js:73499:24 invokeTask http://localhost:4200/polyfills.js:2765:17 runTask http://localhost:4200/polyfills.js:2533:28 http://localhost:4200/polyfills.js:2533:28 drainMicroTaskQueue http://localhost:4200/polyfills.js:2940:25 invokeTask http://localhost:4200/polyfills.js:2845:21 http://localhost:4200/polyfills.js:3885:9 http://localhost:4200/polyfills.js:3911:17
