### Symfony version(s) affected 6.3.4 ### Description Using [Redis 6.0.1](https://pecl.php.net/package/redis) I see this deprecation being reported on my CI: > Redis::scan(): Passing null to parameter #4 ($type) of type ?string is deprecated I don't believe this will be fixed with https://github.com/symfony/symfony/pull/51754 (I know it's not yet tagged). ### How to reproduce I believe this happens when you create a Redis connection from the Cache component. ```php $client = RedisAdapter::createConnection( 'redis://localhost' ); ``` ### Possible Solution _No response_ ### Additional Context - https://github.com/symfony/symfony/pull/51133 - https://github.com/symfony/symfony/pull/51754
