compodoc: [BUG] Lazy loaded routes are not documented

Overview of the issue

Lazy Loaded routes are not showing in documentation:

Operating System, Node.js, npm, compodoc version(s)

OS: Windows Node: 12.8.0 npm: 6.10.2 Angular CLI: 9.1.0

Compodoc installed globally or locally ?

Tried both

If possible sourcecode of the file where it breaks

Here is part of my app-routing.module.ts

// src/app/app-routing.module.ts
const routes: Routes = [
  {
    path: 'module1',
    loadChildren: () =>
      import('./modules/module1/module1.module').then((m) => m.Module1Module),
  }
]

And for each module, such as Module1:

// src/app/modules/module1/module1-routing.module.ts
const routes: Routes = [
  {
    path: '',
    component: Module1Component,
    data: {
      ...
    },
    canActivate: [AuthGuard],
    children: [
      {
        path: '',
        redirectTo: 'list'
      },
      {
        path: 'list',
        pathMatch: 'full',
        component: ListComponent,
        data: {
          ...
        },
      },
      {
        path: ':id',
        component: DetailsComponent,
        data: {
          ...
        },
      },
    ],
  },
];

If possible your terminal logs before the error

Error during generation of routes JSON file, maybe a trailing comma or an external variable inside one route.

Motivation for or Use Case

It should document all routes in the corresponding section.

Reproduce the error

• Create a new app using the CLI and adding --routing
• Create a new module (ng g m module --routing)
• Add some routes an sample components as previously specified.
• Try to create the documentation (npx compodoc -p tsconfig.json)
