Ingesting edge properties via JSON-LD

Hello-

This is a follow up to support topic https://community.stardog.com/t/edge-property-example-error/2561, which appears to have been closed a while ago. I've come up against the exact same issue - trying to import a JSON-LD file via the HTTP API (or via the Studio Load Data function) that contains edge properties, into a database with "edge.properties" enabled, and am receiving the message "Could not parse JSONLD: invalid @id value: value of @id must be a string." Has there been any progress on this issue? If not, could you suggest an alternate import format that will support ingestion of edge properties? Thanks!

Would it be possible to define (and Stardog to parse) the JSON-LD using the JSON-LD-star approach (JSON-LD-star)?
