ive been trying to get resque to work with heroku. i can successfully get it to work in development mode, however when i try pushing to heroku i get
Errno::E
I got the same thing, so, basically Sidekiq was not grabbing the REDISCLOUD_URL from vars, it was grabbing REDIS_PROVIDER.
heroku config:set REDIS_PROVIDER=REDISCLOUD_URL
It worked like a charm.
