I am trying to utilize a service provider from a custom package:

class ReferralsServiceProvider extends ServiceProvider
    {
        public const PACKAGE_NAME = 'referrals';
    
        /**
         * Perform post-registration booting of services.
         *
         * @return void
         */
        public function boot()
        {
            ...
        }
    
        /**
         * Register the application services.
         *
         * @return void
         */
        public function register()
        {
            $this->app->bind(PreReferralsRepositoryInterface::class, WorkflowPreReferrals::class);
        }

The service provider is registered in the packages composer.json file so it’s auto-registered in the utilizing application.

"extra": {
    "laravel": {
      "providers": [
        "PropelReferralsReferralsServiceProvider"
      ]
    }
  }

However in one of the controllers we have in main application:

class ReferalValidationController extends Controller
{
    protected $referrals;

    public function __construct(PreReferralsRepositoryInterface $referrals)
    {
        ...
    }

I get the error:

Argument 1 passed to AppHttpControllersReferalValidationController::__construct() must be an instance of PropelReferralsRepositoriesPreReferralsRepositoryInterface, instance of PropelReferralsRepositoriesWorkflowPreReferrals given

I know for a fact the service provider is registered as I can change the second parameter of the binding to another class and it will then reflect in the error. Have I missed out something critical in the binding? Its almost as if the controller is unaware of the service provider.
