Could not resolve argument $token on override FOS Controller in symfony 4.3

Firstly, I tried all the questions & answers related to this topic. Additionally and I tried related questions and try to solve it but no success. So please read my question thoroughly.

I want to override a FOS Controller. I successfully redirect but not getting perfect /register/confirm/{token} work . I am getting a token error.

Getting Error: Could not resolve argument $token of "App\Controller\RegistrationController::confirmaction()", maybe you forgot to register the controller as a service or missed tagging it with the "controller.service_arguments"?

My Code

Solution

Don't combine the resource entry with your own controller entry when trying to overwrite the controller action

Change the routing to:

fos_user_registration_register:  
    controller: App\Controller\RegistrationController::registerAction
    path: /register


fos_user_registration_confirm:
    controller:App\Controller\RegistrationController::confirmAction
    path: /register/confirm/{token}

You can also put the routing in your controller with annotations: https://symfony.com/doc/4.1/routing.html
