Argument 3 passed to Sonata\UserBundle\Mailer\Mailer::__construct() must be an instance of Swift_Mailer, instance of Symfony\Component\Mailer\Mailer given, called in /home/madmachine/projects/tmh/var/cache/dev/ContainerJLMEZzW/srcApp_KernelDevDebugContainer.php on line 2259

In my .env

###> symfony/sendgrid-mailer ###
MAILER_DSN=sendmail://default

In mailer.yaml config file:

framework:
    mailer:
        dsn: '%env(MAILER_DSN)%'

in my services.yaml file:

app.admin.user.mailer:
        class: App\Mailer\AdminMailer
        arguments:  ['@router','@twig','@mailer','%fos_user.resetting.email.from_email%','%fos_user.resetting.email.template%']

in my fos_user.yaml file

fos_user:
    db_driver: orm # other valid values are 'mongodb' and 'couchdb'
    firewall_name: main
    user_class: App\Entity\User

    group:
       group_class:   App\Entity\Group
       group_manager: sonata.user.orm.group_manager # If you're using doctrine orm (use sonata.user.mongodb.group_manager for mongodb)

    from_email:
      address: '%sender_mail%'
      sender_name: '%sender_name%'
    profile:
      form:
        type:               App\Form\UserProfileType
    change_password:
      form:
        validation_groups:  [ChangePassword,AppChangePassword, Default]
    resetting:
      retry_ttl: 7200 # Value in seconds, logic will use as hours
      token_ttl: 833600
      email:
        from_email: # Use this node only if you don't want the global email address for the resetting email
          address:       '%sender_mail%'
          sender_name:    '%sender_name%'
        template:   'front/mailforget.html.twig'
    service:
      mailer: app.admin.user.mailer

    }

    public function sendConfirmationEmailMessage(UserInterface $user): void

}

the command app.admin.user.mailer resolve to right service
