Related Customer Events missing barcode in web-pixels-api

[vpawebmaster]

Please list the package(s) involved in the issue, and include the version you are using

With the change to checkout extensions, the only way to add pixels is through the web-pixels-api (Customer Events) but we have found some limitations.

Describe the bug

We are currently trying to add javascript code that requires the use of the products barcode property. The problem is the web-pixels-api does not expose the property "barcode" only SKU. See https://shopify.dev/docs/api/web-pixels-api/standard-events/checkout_completed

Steps to reproduce the behavior:

analytics.subscribe("checkout_completed", (event) => {
  let date = new Date();

    date.setTime(date.getTime() + (86400 * 1000));
    const datestring = date.toISOString().slice(0, 19).replace('T', ' ');

    let barcodes = [];
    const lineItems = event.data?.checkout?.lineItems;
    const lilen = lineItems.length;
  
    for(let i = 0; i < lilen; i++){

        barcodes.push({"gtin": lineItems[i].variant.barcode}
   
    }


    window.gapi.load('surveyoptin', function() {
        window.gapi.surveyoptin.render(
            {
                "merchant_id": 123456789,
                "order_id": event.data?.checkout?.order?.id,
                "email": event.data?.checkout?.email,
                "delivery_country": event.data?.checkout?.shippingAddress?.countryCode,
                "estimated_delivery_date": datestring.split(' ')[0],

                "products": barcodes
    });
    }); 

Expected behavior

lineItems[i].variant.barcode should exist.

Just wondering if this is on anyone's radar. We are still held back from using the new features due to the issue above.
