Error: Multiple root routing modules found

See original GitHub issue

I’m still getting an error while adding lazy loaded routes to my Angular project. According to #87 and #82 the error should be fixed, but it isn’t.

Error:

UnhandledPromiseRejectionWarning: Error: Multiple root routing modules found C:\Users\Toni\Source\test\universe\src\app\lazy\lazy-routing.module.ts, C:\Users\Toni\Source\test\universe\src\app\app-routing.module.ts
    at findRootModule (C:\Users\Toni\Source\test\universe\node_modules\guess-parser\dist\guess-parser\index.js:419:15)
    at exports.parseRoutes (C:\Users\Toni\Source\test\universe\node_modules\guess-parser\dist\guess-parser\index.js:582:31)
    at prerender (C:\Users\Toni\Source\test\universe\node_modules\angular-prerender\build\node\functions\prerender.js:89:54)

I’m using the following commands to create the project:

ng new universe --routing
cd universe
ng generate universal --client-project universe
ng generate module lazy --route lazy --module app
ng build
ng run universe:server
npx angular-prerender

My environment is:

Angular CLI: 8.3.14
Node: 12.12.0
OS: win32 x64
Angular: 8.2.12

And the version of angular-prerender that is being used is 4.1.21.

Is there a workaround or different syntax for adding lazy loaded routes/modules to the project? Are lazy loaded routes actually supported?
