Worker job status not reporting correctly

[rossettistone]

I have a number of workers that return results of the general format:

{
  success: false,
  message: "Some text about what happened."
}

I'm able to receive these results when calling a worker's perform method directly, as worker_message = MyWorker.perform(args).message, but I don't see the message or result showing up in the sidekiq_monitor Results column, although the workers continue to perform normally.

Any suggestions for debugging?
