hey team -- i'm having issues accessing
within an asset context -- the dictionary comes back as None, even when a default has been set. For example, taking this from the docs and adding a default value:
Copy code
import json
from dagster import asset, Field

@asset(config_schema={"person_name": Field(str, default_value="stephen")})
def asset_using_config(context):
    # Note how asset config is also accessed with context.op_config
    <http://context.log.info|context.log.info>(f'hello {context.op_config["person_name"]}')
    return True
returns an error when I click "materialize" in the UI, because the object is empty. (logs in thread). Am I missing something, or is this a bug?

@Stephen Bailey tried the same and you’re right, it does not work with a default value. Tested on 1.0.4
