Whenever a cron job in Rails fails with the production database, an error is not configured

Question

In my Rails application, I use whenever gem runs the Sideqik task. When I run this command manually in the rails console, it works. But whenever cron fails with the following error: it keeps repeating itself in the log. How can i fix this? What is the problem?
