nestjs: Dynamic module for dynamically insert controllers y routes module

Question

im trying to build a dynamic module for dynamically insert additional endpoints to certain routes modules (adding a generic crud endpoints):

crud.module.ts

@Module({})
export class CrudModule {
  static register(config): DynamicModule {
    const controller = getController(config.route);
    return {
      module: TestModule,
      controllers: [controller],
    };
  }
}

getController.ts

function getController(route: string): Type<any> {
  @ApiTags(`${route}`)
  @Controller(`${route}/crud`)
  class CrudController {
    @Get()
    get() {
      return route;
    }
  }

  return CrudController;
}

export { getController };

And adding to specified routes modules

route1.module.ts

@Module({
  imports: [
    CrudModule.register({
      route: 'route1',
    }),
  ],
  providers: [UserService],
  controllers: [UserController],
})
export class Route1Module {}

route2.module.ts

@Module({
  imports: [
    CrudModule.register({
      route: 'route2',
    }),
  ],
  providers: [UserService],
  controllers: [UserController],
})
export class Route2Module {}

routes.module.ts

    @Module({
      imports: [Route1Module, Route2Module],
    })
    export class RoutesModule {}

The problem is that the routes generated from CrudModule only is being mapped for the first imported route module (in this case, just for Route1Module), I need a bit help here for get mapping the routes from crud for every Module where is being registered

================ EXTRA INFO

Adding some logs about is loading the CrudModule in the different route modules

@Module({})
export class CrudModule {
  static register(config): DynamicModule {
    console.log({ route: config.route })
    const controller = getController(config.route);
    return {
      module: TestModule,
      controllers: [controller],
    };
  }
}

The log trigger both module loaded, but only once instance of CrudModule is initialised

============= SOLUTION

Thinking about the dependencies initialised and the overriding between controllers/modules naming.

I testing about to dynamically change the name of controller loaded by each module where is being used

@Module({})
export class CrudModule {
  static registre(route: string): DynamicModule {
    const Controller = getController(route);
    Object.defineProperty(Controller, 'name', { value: `${route}Controller` });
    console.log(Controller);
    return {
      module: CrudModule,
      controllers: [Controller],
      providers: [Controller],
      exports: [Controller],
    };
  }
}

I got finally both dynamic controllers being initialised and working correctly

[class route1Controller]
[class route2Controller]
