Issue with v3.3.0, The property 'args' is not defined for Que::Scheduler::EnqueuedJobType

[Sylphias]

Hello,

I've been trying to run que-scheduler and I ran into this issue

NoMethodError: The property 'args' is not defined for Que::Scheduler::EnqueuedJobType.

This is following the same instructions on the Readme.

I've tried adding arguments purposely to the jobs and inside que_schedule.yml

I dug into the code and noticed this

 class EnqueuedJobType < Hashie::Dash
      property :args
      property :queue
      property :priority
      property :run_at, required: true
      property :job_class, required: true
      property :job_id, required: true
    end

Args are defined but somehow the scheduler when creating the job, cant seem to add the arguments to the class. Possibly from args: data.fetch(:arguments) (to_enqueue.rb)

The fix I've done was to revert back to 3.2.8 and then everything was working again.

Interesting. Agreed, it looks like it should work as args is defined. Can you:

1. Tell me if you are using ActiveJob
2. Share the PG, Rails and Ruby version
3. Post an example of the section of the que-schedule.yaml file that shows the error

More of the stack trace might help too...

I am going to guess this is a serialisation issue where the tests are using symbols, but a roundtrip to the DB is returning strings. That area of code has changed in multiple places over the years, both inside que-scheduler and outside areas including que and the pg gem.

Thank you for raising this.

Ah, unfortunately. I dont have the stack trace anymore and I'm rushing a project right now to help revert the project to the previous state in which I found the bug in.

1. I was not using activejob
2. PG : 11.6 (running on docker alpine), rails 5.2.4.2, ruby 2.6.5

DailyReportJob:
  cron: "15 0 * * *"

I've also tried the custom name method with class and args defined. (even purposely putting an args to the job)

Off the top of my head, the tracestack I remember pointed to Hashie::Dash. I assume that there might be some issue with the parsing there.

I'll try to see if I can find some time to dig deeper into this. Thank a lot mate!

The way args are handled has been changed very slightly in 3.4.0 (support for hashes and nils was added). I'd be interested to hear if you see any difference or improvement.

I've ran into this issue as well when upgrading to v3.4.0 with que v0.14.3
