Hi @anon39848301, thanks for the prompt reply.
I had a look at handling-input-values and I’ve tried to define it as product.id as suggested by the documentation. Still when I look at the interface I see a gray field (not editable) with the following message underneath it: “The search on the referenced collection is not authorized.”
Also, I don’t want all the products, I need to scope them with something like Product.available. Is this possible?
