#################################################################################
REDIS_PROVIDER should be set to the **name** of the variable which contains the Redis URL, not a URL itself.
Platforms like Heroku sell addons that publish a *_URL variable. You tell Sidekiq with REDIS_PROVIDER, e.g.:
REDIS_PROVIDER=REDISTOGO_URL
REDISTOGO_URL=redis://somehost.example.com:6379/4
Use REDIS_URL if you wish to point Sidekiq to a URL directly.
This configuration error will crash starting in Sidekiq 5.3.
