vRA 7.0 - Starting XaaS blueprints from API

Hi,

Has anyone managed to launch a XaaS blueprint from the API in vRA 7.0.0 (or later)?

When using the same method that I use for standard blueprints I get an error:

500 Internal Server Error - System exception. getInstanceSpecificSchema for (clsid=asd.catalogItem, cid=7223db0d-7412-4499-a620-196e4ab24e29)

Method used:

POST to /catalog-service/api/consumer/entitledCatalogItems/7223db0d-7412-4499-a620-196e4ab24e29/requests

This is on a XaaS blueprint with no inputs.

Thanks in advance.
