Shopfront hydrogen custom cart_attribute POST to shopify backend

Technical Q&A
1

Hi, I’m trying to create custom cart_attribute, but I’m not able to find that cart_attribute that I POST with graphQL in shopify backend. Am i missing anything?

Here’s what I did

And also I wired that into cart action

if (!cartId) {
        result = await cartCreate({
          input: countryCode
            ? {lines, buyerIdentity: {countryCode}, attributes}
            : {lines, attributes},
          storefront,
        });
      } else {
        result = await cartAdd({
          cartId,
          lines,
          storefront,
        });
      }

I’m sure the custom property is wired in this cart, so the question is how do i checkout this custom data?

I just solved the issue. I need to put that in lines array
