Error service symfony : A namer must be configured

I want to use create folder function with vich considering id.

My service:

<?php

namespace App\Service\Namers;


use Vich\UploaderBundle\Mapping\PropertyMapping;
use Vich\UploaderBundle\Naming\DirectoryNamerInterface;
use App\Entity\Users;

class VichNamer implements DirectoryNamerInterface {

    public function directoryName(object $object, PropertyMapping $mapping): string {
        return 'test';
    }
    
}

my vich_uploader.yaml:

vich_uploader:
    db_driver: orm

    metadata:
        type: attribute

    mappings:
    
        tattoo_images:
            uri_prefix: /images/
            upload_destination: '%kernel.project_dir%/public/images/'
            directory_namer: App\Service\Namers\VichNamer

My services.yaml:

parameters: images_directory: '%kernel.project_dir%/public/uploads'

services:
    # default configuration for services in *this* file
    _defaults:
        autowire: true      # Automatically injects dependencies in your services.
        autoconfigure: true # Automatically registers your services as commands, event subscribers, etc.

    # makes classes in src/ available to be used as services
    # this creates a service per class whose id is the fully-qualified class name
    App\:
        resource: '../src/'
        exclude:
            - '../src/DependencyInjection/'
            - '../src/Entity/'
            - '../src/Kernel.php'

    # add more service definitions when explicit configuration is needed
    # please note that last definitions always *replace* previous ones
    App\EventSubscriber\EasyAdminSubscriber:
        tags:
            - { name: 'doctrine.event_subscriber', event: preUpdate }
    App\Service\Namers\VichNamer:
        public: true
        tags: 
            - { name: 'vich.namedirectory' }

My error:

A namer must be configured.

I user symfoy 6.2

thank you

The namer is used to name the files and directories it saves to the filesystem You can add nammer by default like this in your config:

vich_uploader:
.....

  mappings:

    tattoo_images:
        uri_prefix: /images/
        upload_destination: '%kernel.project_dir%/public/images/'
        directory_namer: App\Service\Namers\VichNamer
        namer:
          service: Vich\UploaderBundle\Naming\PropertyNamer
          options: { property: 'slug' }

You can see all options working with namer here : namers
