Hi @daniskazan

The problem is how you use cashews

redis_client = cashews.cache.setup(settings_url=REDIS_URL,db=1,wait_for_connection_timeout=0.5,safe=False,enable=True)

That is not a right way and there are no examples with a code like that

Take a loot at readme

Do not use returnings of setup

I also have this error when using redis,
in-memory cache are working perfectly fine
AttributeError: 'Redis' object has no attribute '_client'

its my first time using cache manager, i need to speed up some variable load than directly using my mysql connections.
