Is it possible to read the metadata when handling input in an I/O manager? In the

handle_output

method, I have attached some metadata

context.add_output_metadata(
            {"delivery_date": obj.date.isoformat(timespec="milliseconds")}
        )

then I tried to read this key in the

load_input

method

context.upstream_output.metadata["delivery_date"]

but the key doesn't exist. Is there a way to do this?

hey @moritz we have an issue open for this here https://github.com/dagster-io/dagster/issues/9076

Thank you for the link to the issue. I'm trying to retrieve the data from an

InputContext

which seems to be a scenario not covered by the issue?

yeah you’re case is more covered by this issue, but it’s likely all the same base cause so it was marked as a duplicate https://github.com/dagster-io/dagster/issues/12873

I see, thanks ☺️
