Handling nested references in Sanity preview function

Hey everyone! 👋
I’m trying to get a nested array of referenced objects inside the preview function, but I’m running into some issues. My schema looks something like this:


The cards array contains references to another document type, and each referenced document has a theme.hex field. However, I’m not sure how to correctly select the nested theme values from these referenced objects.

I’ve checked the
Sanity docs on previews , but it only covers direct references, not arrays of references.
Is there a recommended way to handle this in select? Or do I need to resolve the references manually in prepare?

Thanks in advance!

Preview use a weird syntax that doesn’t translate to GROQ in some cases. Notably, you won’t use square brackets and I think you can treat them as if they’re dereferenced. Can you try changing theme (in your select) to:

Or maybe (I don’t know your schema):

Great!
Unfortunately, no. You’d need to request them individually, getting as many as you need in the `select`:


And then managing those in your

prepare

function.

Ok, I see. Thanks for the quick answer

Once you do them manually like that, the main 'cards' should contain them all. Weird quirk. I've dug into the sanity logic a few times trying to 'fix' this and it is annoying but I haven't solved it yet.
