valkey server on RDB mode errors in github CI with some clients

[amirreza8002]

hi
i'm developing the django-valkey package
at the moment i'm working on async clients

i have a ci configured to run tests: ci.yml
which uses a sh file to run servers

normally, tests run fine, but with the two new clients (async sentinel, async herd) valkey breaks
docker log

pytest log start
pytest log error

it is weird that all other clients work fine
