Symfony version(s) affected

6.3.4

Description

Using Redis 6.0.1 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 #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.

$client = RedisAdapter::createConnection(
    'redis://localhost'
);

Possible Solution
