@dev-zero do you have sample payloads for what brought this out exactly?

Could you also sign-off your commit?

@mraineri sure.

This is the error:

$ uv run scripts/rf_sys_inventory.py --debug
'@odata.id'

This is the relevant part of the log file:

This is actually a bug in the service; having an empty reference object like that is illegal per Redfish. This would not pass conformance testing.

Have you raised this bug with HPE?
