Yo - I have defined a custom

DagsterType

and annotated the function return value for my

@asset

definition. In the UI, the asset is being shown to return

Any

, not my custom type. Type definition

GeoJSONFeatureCollection = DagsterType(
    name="GeoJSONFeatureCollection",
    type_check_fn=is_geojson_feature_collection,
    typing_type=Dict[str, Any],
)

Asset definition (abridged):

@asset(
    ...
)
def nifc_active_fire_perimeters_geojson(
    context: OpExecutionContext,
) -> GeoJSONFeatureCollection:
    ...

Hm the type inference code should be able to figure this out… Flagging to the team

Thank you. Looks like I just didn't understand the docs, and maybe also not Python 😁

Anyone who says they understand python is lying
