When installing flask-redis via pip, redis-py gets automatically installed as a dependency of flask-redis. However, the correct version of redis-py is not defined. This package (flask-redis==0.4.0) works fine with redis==3.5.3, but saving values via hmset throws an error using the newer version redis==4.0.2, which pip currently chooses to install.
