routing gives me 404 when I try to access to login

Question

In my angular app(13 version) the routing doesn't work. I need to do the login so I do this in my angular routing:

const routes: Routes = [ {
  path: 'idm/login', loadChildren: () => import("./components/login/login.module").then(m =>
    m.LoginModule)
}

@NgModule({
  imports: [RouterModule.forRoot(routes,{ scrollPositionRestoration: 'enabled' })],
  exports: [RouterModule]
})

So I start my app with:

ng build --watch --base-href /Documental/

and when I go in :

http://localhost:8080/Documental/idm/login

it gives me 404. Anyone can help me?
