Sidekiq : Throwing Error Message

[puneetgaurr]

I am using Sidekiq for the background process and creat a very simple application to validate Sidekiq functionality. I am getting success response but getting failure message when calling it through sidekiq. Please help me resolve this issue.

Error Message :
