nestjs - using hbs / static content with controllers in subfolders

Question

Using hbs as described in the nestjs docs works fine with the top level app controller.

But for controllers which are located in subfolders the static content are not rendered / found by hbs.

main.ts (as usual):

async function bootstrap() {
  try {
    const app = await NestFactory.create<NestExpressApplication>(AppModule);
    ...
    app.useStaticAssets(join(__dirname, '..', 'public'));
    app.setBaseViewsDir(join(__dirname, '..', 'views/web'));
    app.setViewEngine('hbs');
    ...
  } catch (error) {
    ...
  }
}
bootstrap();

folder structure:

public
  common.css
  work1_logo.png
src
  work1
    work1.controller.ts
    work1.module.ts
    work1.service.ts
  app.controller.ts
  app.module.ts
  app.service.ts
  main.ts
  ...
views
  web
    template1.hbs

In the app.controller.ts, hbs renders the template1.hbs using common.css and work1_logo.png In the work1.controller.ts, hbs renders the template1.hbs WITHOUT common.css and work1_logo.png.

Conclusion:

It seems that

app.setBaseViewsDir(join(__dirname, '..', 'views/web'));

is working well, but not

app.useStaticAssets(join(__dirname, '..', 'public'));

Any ideas what I can do to keep my folder structure?

(Otherwise all controller have to be located on top level. But this cannot be the idea of a modular structure.)
