I have upgraded to Angular 8 and found the in lazy loading modules routing. While upgrading CLI itself changed all my lazy loading routes according to new syntax.

| },

            loadChildren: () => import('./modules/abc/abc.module').then(m => m.AbcModule)

| },
| {


children: [
{path: '',
pathMatch: 'full',

canActivate: [AuthGuard],
},
{

loadChildren: () => import('abc/abc.module').then((m) => m.AbcModule),
}]
