Sonataadminbundle: argument "$code" of method "Sonata\AdminBundle\Admin\AbstractAdmin::__construct()" has no type-hint

[ArchTaqi]

Hy folks, I just upgraded my Symfony version to 4 and Sonata admin to 3 and gets below error;

Cannot autowire service "admin.app.business": argument "$code" of method "Sonata\AdminBundle\Admin\AbstractAdmin::__construct()" has no type-hint, you should configure its value explicit  
  ly.

Is there anything changed, I need to add ?

This bundle doesn't have native support for autoconfiguration on admin services. You must define your services explicitly or try with kunicmarko/sonata-auto-configure-bundle to autoconfigure your admin services.
