What this PR changes/adds
Adds a check to the
DatasetResolverImpl
to only return a dataset if it has an offer attached.Why it does that
To avoid exposing sensitive information (asset metadata) if the requesting participant is not authorized to see it.
Further notes
Also adds a check for
query
andgetById
to immediately return if no valid contract definitions exist for the requesting participant, as then no offers would be returned anyway, so it doesn't make sense to query and evaluate the assets in that case.
