Subject: [PATCH] fix: add support for legacy mode The latest release checks
 for Redis v4 but doesn't check if the user enabled legacyMode. If legacyMode
 is enabled, subscribe functions are causing errors.

Unfortunately the Redis client API currently doesn't offer any way to
check if legacy mode is enabled which is the reason why it I have to
check it in this hacky way.
