Hi there, I’m trying to validate the schema in my

config.yaml

using

make_values_resource

. My code snippet is as follows:

"county_globals": make_values_resource(
            account_url=str,
            download_container=str,
            upload_container=Noneable(str),
            local_dir=Noneable(str),
        ),

I want to specify that the local_dir has to be either None or a specific string value (such that I can verify it’s in the .gitignore file). However, the dagster typing doesn’t seem to support string literals. Ideally, I’d want something like

local_dir=Optional[Literal['a/specific/path']]

. Is there a way to do this type of validation?
