Hi Umbraco people I have a content delivery query that isn't quite behaving like i am expecting it to. I have a body property that's a block grid. inside that block grid, i've added a component for a carousel, which takes a list of content items (articles). That's all fine, but in the delivery api response the properties of the articles aren't expanded. I have my query set to expand all. i have also tried to explicitly expand the property (possibly incorrectly). What is the right way to be able to expand these nested content properties? my query:

https://localhost/umbraco/delivery/api/v2/content/item/%2F?expand=properties%5B%24all%5D&fields=properties%5B%24all%5D

response:
