I configured everything like in this how to: https://gtm-server.com/facebook-conversion-api-for-shopify/
Now I get also the following error for View Content and Add to Cart events
You’re sending the same event ID for many instances of your AddToCart events. Event IDs are unique identifiers that are used to deduplicate identical events received from your pixel and the Conversions API so they’re not counted twice.
Please help to fix
