Doctrine multiple databases mapping not working

Here is my config :

doctrine:
    dbal:
        default_connection: default
        connections:
            default:
                url: '%env(resolve:DATABASE_URL)%'

                naming_strategy: doctrine.orm.naming_strategy.underscore_number_aware
                auto_mapping: true
                mappings:

                        prefix: 'App\Entity'
                        alias: App
            sqlite:
                connection: sqlite
                mappings:
                    SQLite:
                        is_bundle: false
                        type: annotation

                        prefix: App\Entity\EntitySqlLite
                        mapping: true


when@test:
    doctrine:
        dbal:
            # "TEST_TOKEN" is typically set by ParaTest
            dbname_suffix: '_test%env(default::TEST_TOKEN)%'

when@prod:
    doctrine:
        orm:
            auto_generate_proxy_classes: false
            proxy_dir: '%kernel.build_dir%/doctrine/orm/Proxies'
            query_cache_driver:

            result_cache_driver:
                type: pool
                pool: doctrine.result_cache_pool

    framework:
        cache:
