Rack::Cache cache error: Unknown storage provider

[jfloff]

I have the latest version 1.10.0 installed and I'm running on Rails 6.

My production.rb configuration looks like this:

config.action_dispatch.rack_cache = {
    metastore: ::Rack::Cache::MetaStore::Redis.new("#{ENV['REDIS_TLS_URL']}/1/metastore", ssl_params: { verify_mode: OpenSSL::SSL::VERIFY_NONE }),
    entitystore: ::Rack::Cache::EntityStore::Redis.new("#{ENV['REDIS_TLS_URL']}/1/entitystore", ssl_params: { verify_mode: OpenSSL::SSL::VERIFY_NONE }),
  }

(This is a newer version of issue #188)
