Getting this error in Heroku logs: Don't know how to build task 'jobs:work'

Question

I've been troubleshooting a rails app I pushed to an existing Heroku app. Whenever I submit user input from the home page, I receive a 500 error: We're sorry, but something went wrong.

This is what I get back when I run heroku logs :

2014-12-15T22:59:50.824951+00:00 app[worker.1]: rake aborted!
2014-12-15T22:59:50.824977+00:00 app[worker.1]: Don't know how to build task 'jobs:work'

I'm not sure what steps I should take fix this, so any insights would be greatly appreciated!

Answer 1

This is more of a work-around than a solution:

Add a (blank) rake task called jobs:work .

# lib/tasks/jobs.rake
namespace :jobs do
  task work: :environment do |t|
  end
end

Answer 2

I started getting this error when my Hobby dyno went over the hours allowed per month

Run heroku run rake -T|grep jobs and if you get Free app running time quota exhausted then there you have it...
