Hey all, I have a question with dagster.StringSource. How do i set the default value to pick up from environment variables? For example:

"gcp_project": dagster.Field(
            dagster.StringSource,
            description="project name",
            is_required=False,
            default_value=os.getenv("GCP_PROJECT", "my-gcp-project"),
        ),

The default_value doesn't seem like the most "dagster" way to do it. Should it be {env: GCP_PROJECT}?

Hey Charles -

default_value={"env": "GCP_PROJECT"}

looks right to me, yeah

thanks daniel! i'll test this out.
