Gigalixir GenServer stopping due to nil schedule

[sfsekaran]

Not certain what's going on here. Quantum works fine on my local, but on "production" (Gigalixir), Quantum fails with the following backtrace/error.

It seems, after looking at the log, that nil is being passed as the schedule argument, which is why it's failing. But past that I'm not sure why it's doing this.

My test config looks something like this:

config :violeta, Violeta.Scheduler,
  jobs: [
    test: [
      schedule: "* * * * *",
      task: {
        Violeta.Pigeon,
        :test,
        [%{
          from: "15555555555",
          to: "15555555555",
          message: "Testing the scheduler."
        }]
      }
    ]

Any thoughts?
