oneOf appears to not work correctly (Being treated like allOf)

Inizia riproducendo l’errore di validazione dell’aggiornamento segnalato con lo schema e il payload contenenti VpcLinkId e BaseURI. Confronta i risultati della validazione per esattamente uno, entrambi e nessuno dei rami oneOf; il lavoro è completato quando un ramo valido viene accettato, mentre le combinazioni non valide producono gli errori previsti.
