Is this a regression?

Not, this is a older problem, i reported previusly in angular/angular-cli#13006 without providing a repo.

Description

I receive a Unexpected value 'LayoutModule' error when building a library with a single NgModule dependency (one NgModule depends on other).

🔬 Minimal Reproduction

This repo contains a minimal example of the issue: https://github.com/prodisign/bug-reporting ng build rh

Edit: In the repo, I am using a complex module disposition, doing use of secondary entrypoints. But other simplest dispositions throwns the same error.

Im reported the same issue at https://github.com/ng-packagr/ng-packagr/issues/1444.

@IgorMinar i am going to remove the ivy and ngcc labels as this is a bug in the VE metadata bundler.

[alan-agius4]

This seems related to barrel files.

In projects/prodisign/rh/client/src/public_api.ts change export * from './layout to export * from './layout/index';

I am moving this to the FW repo as it’s a compiler bug.
