Another one - I was playing with

dagster.*input_hydration_config*

(what a name, btw 😃 ). I wanted to build an object from a dictionary. The documentation states:

config_cls (Any) – The type of the config data expected by the decorated function. Users should provide one of the built-in types, or a composite constructed using 

Selector()

 or 

Permissive()

.

Dict is one of the listed built-in types yet it's not a subclass of ConfigType thus it fails. So it's kinda confusing behaviour.

apologies, you're hitting all the rough edges in our docs. you should be able to pass a dict literal, or construct what you want using
