I found a mistake in using redis as backend

[aeasringnar]

When I use redis as the backend of the cache, I use cache_response, but there is an error: STACK_GLOBAL requires str.

is drf-ex issue or django-redis?

@aeasringnar Please provide more info, like versions of libraries you use and example of code to reproduce it. I guess, it's problem in your code or outdated django-redis.
