Pinterest Tag Health Make sure you are including Product IDs in your Add to Cart events. SHOPIFY

Make sure you are including Product IDs in your Add to Cart events. A Product ID can be any format that you choose as long as it matches the format used by your Catalog.

I am getting this error on Pinterest tag health and I don’t know how to fix it. I am using Shopify. I have tried to add this code to submit button:

onclick="pintrk('track', 'addtocart');"

But it is not working. Is this some kind of bug?
