Object of class App\HelloWorld\Communication\Controller\HelloWorldController could not be converted to string

[Asisyas]

Method 'index2' is not defined in Controller.

$httpFacade
     ->createRouteBuilder()
     ->setController([HelloWorldController::class, 'index2'])
      ->setUri('/')
      ->setName('hello_world')
      ->build();

Exception: ContainerExceptionInterface with message: Object of class App\HelloWorld\Communication\Controller\HelloWorldController could not be converted to string

Accepted: RouteConfigurationException

Should be fixed in the Autowire component.
