When I try to create a scheduled_actions - schedule in a Resource I get the following error:
15:32:00.625 [error] GenServer {Oban.Registry, {Oban, {:plugin, Oban.Plugins.Cron}}} terminating

The simplest reproduction that I can make that throws the error is as follows:
defmodule Helpdesk.Support.Ticket do
use Ash.Resource,
otp_app: :helpdesk,
domain: Helpdesk.Support,
extensions: [AshOban]
oban do
domain Helpdesk.Support
scheduled_actions do
schedule :test_action, "* * * * *" do
worker_module_name Helpdesk.Support.Ticket.AshOban.ActionWorker.TestAction
end
end
end
actions do
action :test_action do
run fn _input, _ ->
IO.inspect("Ran the text action")
:ok
end
end
end
end
I’ve tried using the main branch in ash_oban from Github and I still get the same error.
I’m not sure if this is something underlying in Oban or on our end…more likely to be us than them. Could you please create a reproduction repository and open an issue on AshOban?
