Cyclic dependency error when injecting RouteGeneratorService

[jasonhjohnson]

I'm getting a Cyclic dependency error when injecting the RouteGeneratorService into a view model.

The relevant code is as follows:

app.routes.ts

export const personas = {
  route: 'personas',
  name: 'personas',
  moduleId: PLATFORM.moduleName('modules/personas/personas-section.vm', 'personas'),
  nav: true,
  title: 'Personas'
};

route-generator.service.ts

private routeTree: ITreeConfig[] = [
    appRoutes.welcome,
    appRoutes.users,
    {
      ...appRoutes.personas,
      subroutes: [
        personaRoutes.select
      ]
    }
  ];

personas-section.vm.ts

import { autoinject } from 'aurelia-framework';
import { Router, RouterConfiguration } from 'aurelia-router';

import { RouteGeneratorService } from './../../services/route-generator.service';

@autoinject
export class PersonasViewModel {

  public router!: Router;
  public heading = 'Personas';

  constructor(
    private routeGeneratorService: RouteGeneratorService,
  ) { }

  public configureRouter(config: RouterConfiguration, router: Router): void {
    config.map(this.routeGeneratorService.getRoutesConfigByParentRouteName('personas'));

    this.router = router;
  }
}

The following file is the file that fails to inject the routeGeneratorService:

select.vm.ts

import { autoinject } from 'aurelia-framework';
import { Router, RouterConfiguration } from 'aurelia-router';
import { RouteGeneratorService } from './../../services/route-generator.service';

@autoinject
export class PersonasSelectViewModel {
  public router!: Router;
  constructor(
    private routeGeneratorService: RouteGeneratorService
  ) { }
}

Any help is appreciated.

I was able to resolve build issues by setting chunksSortMode to none for the HtmlWebpackPlugin. Not sure precisely why this works but there you go.

plugins: [
new HtmlWebpackPlugin({
    // This is required or else the build fails for unknown reasons.
    // https://github.com/jantimon/html-webpack-plugin/issues/981#issuecomment-399140618
    chunksSortMode: 'none'
}),
