Hello @warren,
As per most of my responses, please don’t take this as gospel, I’ve been trying all sorts of stuff, and the last thing I want to do is lead people up the wrong garden path.
However. If you see this reply on this post:
Using the DocumentItemRepository might help you get the content via the unique property for your card item.
import { UmbDocumentItemRepository } from '@umbraco-cms/backoffice/document';
and
let { data } = await this.#itemRepository.requestItems( [unique] );
I might be wrong, but .requestItems is looking for an array of unique’s.
Thank you,
Rob
