Description

I have added Angular SSR in an existing Angular app with routing enabled and when I run ng build I get the following error:

The 'products/:id' route uses prerendering and includes parameters, but 'getPrerenderParams' is missing. Please define 'getPrerenderParams' function for this route in your server routing configuration or specify a different 'renderMode'.

Minimal Reproduction

1. Create a new Angular CLI 19 application
2. Create a route in the app.routes.ts file with parameter
3. Run ng add @angular/ssr
4. Run ng build
