No deliveryGroups returned when adding a cart line item.

Hi !

I’m trying to get an estimate cost of shipping in my Hydrogen app.

For that, I add a cart line item, which creates a cartId.

  const result = await context.cart.addLines([
    {
      merchandiseId: variantId,
      quantity: 1,
    },
  ]);

I then mutate succesfully the “cartBuyerIdentityUpdate”, providing the country, province and zip code.

  const buyerIdentityResponse = await context.storefront.mutate(
    UPDATE_CART_BUYER_IDENTITY_MUTATION,
    {
      variables: {
        cartId,
        buyerIdentity: {
          countryCode,
          deliveryAddressPreferences: [
            {
              deliveryAddress: {
                zip: postalCode,
                country: country,
                province: provinceCode,
              },
            },
          ],
        },
      },
    },
  );

But it always returns an empty array for deliveryGroups.
When I try the same cartId in the checkout page, it works perfectly.

Am I missing something ? Any idea why deliveryGroups would come back unpopulated everytime ?

Thanks for your help !
