Excon::Error::NotFound - Heroku Delayed Jobs

[patricklindsay]

Since upgrading to 2.2.0 I've been receiving the following error when a job is created in Heroku.

Excon::Error::NotFound: Expected([200, 201, 202, 204, 206, 304]) <=> Actual(404 Not Found)

On the brightside updating did fix DJ logging in Heroku. (#89) However will have to downgrade until can figure out what is causing this.
