🐞 bug report

Affected Package

The issue is caused by package @angular/compiler and/or @angular/core and/or @angular/router

Is this a regression?

Yes, the previous version in which this bug was not present was: 7.2.1

Description

I try to load a project library (named shell) as a route “loadChildren”, with 2 différents option :

• loadChildren: () => import(‘shell’).then(m => m.ProfileModule)
• loadChildren: () => ProfileModule

This 2 ways work correctly on dev mode, but failed on AOT builded mode with an error message. And the route is not loaded.

🔬 Minimal Reproduction

ProfileModule (as an angular library named “shell” on the CLI project) :

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { MatButtonModule } from '@angular/material/button';
import { MatCardModule } from '@angular/material/card';
import { MatIconModule } from '@angular/material/icon';
import { MatListModule } from '@angular/material/list';
import { FlexLayoutModule } from '@angular/flex-layout';

import { ProfileComponent } from './profile/profile.component';
import { TranslateModule } from '../translate/translate.module';
import { GhostModule } from '../ghost/ghost.module';
import { DataModule } from '../data/data.module';
import { ProfileRoutingModule } from './profile-routing.module';
import { ProfileCardComponent } from './profile-card/profile-card.component';

@NgModule({
  declarations: [
    ProfileComponent,
    ProfileCardComponent
  ],
  imports: [
    CommonModule,
    MatCardModule,
    MatListModule,
    MatButtonModule,
    MatIconModule,
    TranslateModule,
    FlexLayoutModule,
    GhostModule,
    DataModule,
    ProfileRoutingModule
  ],
  exports: [
    ProfileCardComponent
  ]
})
export class ProfileModule { }

AppRoutingModule (as an angular project from the same CLI project)

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

import { SecureGuard } from 'shell';

import { HomeComponent } from './home/home.component';

export function loadProfile() {
  return import('shell').then(m => m.ProfileModule);
}

const routes: Routes = [{
  path: '',
  canActivate: [SecureGuard],
  children: [{
    path: '',
    component: HomeComponent
  }, {
    path: 'profile',
    loadChildren: loadProfile // Here the error at runtime, the error message appear when I go to /profile
  }, {
    path: '**',
    component: HomeComponent
  }]
}];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

Anything else relevant? I try to use on different CLI projects a Profile module from a CLI library (all on the same CLI project). This is not possible since angular 8.0.0
