jinja caching won't have exception while having redis failure

[dzpt]

I constantly got this error inside of jinja file
using {% cache 900,'home' %}{% endcache %}

redis.exceptions.ResponseError: MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk. Commands that may modify the data set are disabled. Please check Redis logs for details about the error.

It breaks the whole page if there is error in redis.

python 3.8.1
flask-caching 2.2.0
