Looking for advice on 'AttributeError: No option 'worker_cores' available' when setting cluster-options

Okay, I see. Printing dict(options) does output the keys:
'instance_type', 'worker_resource_allocation', 'image', 'environment', 'idle_timeout_minutes'
But not the worker-options that I normally set.

I moved the discussion to here.
