Expected Behavior

There shouldn't be error.

More detail

The application running oban_web didn't start oban queue with queues: false. (We are having 2 elixir application. One is for core logic which start oban queue. another one is admin dashboard where oban_web is mounted)

Also no oban pro feature is being used yet(no batching)

sorentwo commented

This is because Oban isn't configured to use the Smart engine. The handler is fixed on main and it'll be in Pro v1.4.8, due out later today.

Thank you. @sorentwo Since we are not using Oban.Pro.Batcher, I assume it's safe to not continue with this version without rolling back?

sorentwo commented

You don't need to roll anything back. If you're not using batches then that error won't impact anything. Switching to the Smart engine or removing oban_pro from your deps until you're ready to start using those features will fix it as well.
