Creating a current Angular SSR project and adding a dynamic host does not work out of the box.

With what library do you have an issue?

native-federation

Reproduction of the bug/regression with instructions

1. Run ng new --ssr
2. Run ng add @angular-architects/native-federation --type dynamic-host
3. Run npm start

Looks like the schematic is missing a curly brace in the bootstrap-server generated file, but even after fixing that I come across multiple other errors while trying to run the local dev server or do a build and serve:ssr command.

Oftentimes, the fstart.mjs cannot locate the ../browser/remoteEntry.json file despite it being there.

node:internal/fs/promises:633
  return new FileHandle(await PromisePrototypeThen(
                        ^

Error: ENOENT: no such file or directory, open '../browser/remoteEntry.json'
    at async open (node:internal/fs/promises:633:25)
    at async Module.readFile (node:internal/fs/promises:1237:14)

    at async createNodeImportMap (file:///my-appt/dist/my-app/server/fstart.mjs:308:20)

  errno: -2,
  code: 'ENOENT',
  syscall: 'open',
  path: '../browser/remoteEntry.json'
}

Expected behavior

Native federation apps should work out of the box with default Angular SSR apps.

Hi,

Thanks for pointing this out. IMHO, we need to adapt to changes in Angular.

Did you find a manual way of making this work?

Best,
Manfred

@manfredsteyer unfortunately, I was not able to. After fixing the bootstrap-server.ts missing closing curly brace, it seems like the build can never find the federation.manifest.json no matter what i do. Even trying to follow your upgrade to v20 guide and moving the bootstrap-server.ts code back into server.ts results in a similar error. I can't figure out why the softarc code can't find the federation files.
