Cannot GET -- when don't find the folder language -- example Cannot GET /fr/pr-home

[ph360]

Which @angular/* package(s) are the source of the bug?

router

Is this a regression?

Yes

Description

In app.routes.ts

import { Routes } from '@angular/router';
import { PrHomeComponent } from './pr-home/pr-home.component';
import { PrContactsComponent } from './pr-contacts/pr-contacts.component';
import { PageNotFoundComponent } from './page-not-found/page-not-found.component';

export const routes: Routes = [
{ path: '', component: PrHomeComponent},
{ path: 'pr-home', component: PrHomeComponent },
{ path: 'pr-contacts', component: PrContactsComponent },
{ path: '**', component: PageNotFoundComponent },
];

In app.routes.server.ts

import { RenderMode, ServerRoute } from '@angular/ssr';

export const serverRoutes: ServerRoute[] = [
{
path: 'pr-contacts',
renderMode: RenderMode.Prerender,
},
{
path: 'pr-home',
renderMode: RenderMode.Prerender,
},
{
path: '**',
renderMode: RenderMode.Client
}
];

• if I change the path: 'pr-home' for one with error, for example pr-homefffff

https://pr360v2--pr360-v2.us-central1.hosted.app/es/pr-homefffff the result i show me the follow message

Page Not Found is the content of component PageNotFoundComponent

there the wildcard route ** if work very good the routes.

• but, if i change the folder the language for one that not exist, for example fr

Cannot GET /fr/pr-home

in this case don't work the wildcard ** in the config the routes.

The result of ng build --localize

This behavior is expected because no Angular application is not mounted at /fr/. The ** route applies after the localized base href. For example, /es/**. This is similar to a missing resource scenario, where a custom middleware in the chain can handle the response.
