zeitwerk-2.1.9, ruby-2.5.5, Rails 6.0 upgrade uninitialized constant ApplicationJob (NameError) about zeitwerk

No, it should definitely work, there must be something else that cause this exception.

Could you shared more details? e.g. the last few lines of the zeitwerk logs, and potentially try to repro in a new app.

@byroot thank you for your reply! In a newly created rails 6 app it works fine. I resolved the issue as it was caused by ApplicationJob being referenced in an initializer by moving the code to config.after_initialize.
