Hello. I am trying to build an asset that returns an

Output

object where

value: str

and

metadata: dict

for example:

@asset
def my_asset() -> Output:
  # do stuff
  return Output(
    value="a_string",
    metadata={"meta": "data"}
  )

I am unsure of how to properly type check that

value

is a string and

metadata

is a dict in

Output

Any suggestions? Python and Dagster types are a bit new for me.

Hi Tim, you can use MetadataValue to control the output of metadata: https://docs.dagster.io/_apidocs/ops#dagster.MetadataValue

Thanks for the feedback!
