Question

当我进入子路线然后选择浏览器后退按钮后退时，我收到以下错误。我已经研究过这个错误，似乎没有任何描述的问题。例如，我的所有父路由都有路由器插座。有趣的是错误是间歇性的。它并不总是发生，但最终会发生。

错误：

我按如下方式设置我的项目和路线：

应用程序路由：

const routes: Routes = [
  {
    path: '',
    redirectTo: '/start/landing',
    pathMatch: 'full'
  },
  {
    path: 'start',
    component: StartComponent,
    children: [
      { path: 'landing', component: LandingPage }
    ]
  },
  {
    path: 'signup-login',
    component: SignupLoginComponent,
    children: [
      { path: 'email-login', component: EmailLoginPage },
      { path: 'linkedin-login', component: LinkedinLoginPage },
    ]
  },
  {
    path: 'dashboard',
    component: DashboardComponent,
    canActivate: [AuthGuard],
    children: [
      { path: 'devices', component: DevicesPage },
      { path: 'device/:id', component: DeviceDetailsPage },

      { path: 'groups', component: GroupsPage },
      { path: 'group/:id', component: GroupDetailsPage },
      { path: 'group-score', component: GroupScorePage },
      { path: 'group-devices', component: GroupDevicesPage },
      { path: 'group-members', component: GroupMembersPage },
      { path: 'group-invite-member', component: GroupInviteMemberPage },

      { path: 'sites', component: SitesPage },
      { path: 'site/:id', component: SiteDetailsPage },
      { path: 'site-score', component: SiteScorePage },
      { path: 'site-devices', component: SiteDevicesPage },
      { path: 'site-tenants', component: SiteTenantsPage },
      { path: 'site-invite-tenant', component: SiteInviteTenantPage },

      { path: 'profile', component: ProfilePage },
      { path: 'cyber-score', component: CyberScorePage },
      { path: '', component: DevicesPage }
    ]
  }
];

应用组件HTML：

<main>
  <router-outlet></router-outlet>
  <notifications></notifications>
</main>

信息中心组件HTML：

<section class="dashboard">
  <toolbar class="main"></toolbar>
  <header class="dashboard-header">

更新：完成错误：

我更改了应用程序的结构，因为此故障单最初是创建的，因此仪表板不再存在且已更改。但错误仍然是一样的。
