Intelligems does not add the _igDiscount line item property when adding to cart

This is applicable only to Shopify Plus stores. When adding a product that's being test to cart, Intelligems should add line item property _igDiscount that indicates the amount of discount to apply to the line item in order to effect the correct price for the user's test group. Some common issues that cause this to not work correctly are:

• The add to cart happened on a page where the Intelligems Javascript was not loaded, such as a landing page that Intelligems has not been integrated with. Check the page source or network traffic to ensure that the Intelligems JavaScript snippet is loading on the page. Learn more about adding the Intelligems JavaScript snippet to your theme here.

• There's an error causing the Intelligems JavaScript to exit early. Check the JavaScript console for errors raised by Intelligems, and check the window.igData.errors object for any suppressed error messages.

• The add to cart is happening via a mechanism that Intelligems does not support, or skipping add to cart altogether. Common examples include quick buy buttons, third-party apps that use Draft Orders or landing pages that use checkout permalinks.
