useCart hook fetches wrong URL

[Chadyka]

Hello!

I am trying to upgrade a client's custom storefront to the new hydrogen-react version, but I'm facing an issue with the useCart hook. Whenever I try to add anything to cart with linesAdd I get an error in the console:

cart-hooks.mjs:27
POST http://localhost:3000/editor/[my-shop].myshopify.com/api/2023-01/graphql.json 404 (Not Found)

This tells me that useCart is fetching the wrong URL. However when I looked at the implementation in cart-hooks.mjs the fetch URL seems to be coming from a useShop hook, which if I call from the client, it returns the valid api URL from getStorefrontApiUrl. So why is useCart prepending the current window location to the api URL?

Can you provide an example for us to look at? Thanks!
