Description

Hi,

When running the following command :

bin/console doctrine:cache:clear-result

I'm getting the following error :

PHP Deprecated:  strlen(): Passing null to parameter #1 ($string) of type string is deprecated in /var/www/html/vendor/symfony/cache/Traits/RedisTrait.php on line 390

Deprecated: strlen(): Passing null to parameter #1 ($string) of type string is deprecated in /var/www/html/vendor/symfony/cache/Traits/RedisTrait.php on line 390

Here is my cache config :

snc_redis:
    clients:
        default:
            type: predis
            alias: redis_client
            logging: false
            dsn: '%env(REDIS_URL)%'

framework:
    cache:
        prefix_seed: xxx
        app: cache.adapter.redis
        default_redis_provider: snc_redis.redis_client
        pools:
            doctrine.metadata_cache_driver:
                adapter: cache.app
            doctrine.result_cache_pool:
                adapter: cache.app
            doctrine.system_cache_pool:
                adapter: cache.app
            doctrine.second_level_cache_pool:
                adapter: cache.app
            cache.api_rate_limit:
                adapter: cache.adapter.redis
                provider: snc_redis.redis_client

The doClear in RedisTrait should return '' and not null :

$prefix = $this->redis->getOptions()->prefix ? $this->redis->getOptions()->prefix->getPrefix() : '';

Thanks in advance,
Julien
