AddToCart Event Not Deduplicated
You’re sending AddToCart events across the pixel and server connection, but they’re not deduplicated since you didn’t add an event_id parameter for this event. Without an event_id for this event, your AddToCart events will be counted twice since they cannot be deduplicated.
This may cause problems with the attribution of your ad campaigns.

`How to solve the problem
To solve the problem you will need to use the solution below.
Once you have resolved the issue in your website’s code, you can mark it as resolved. This will move the problem to the Previously Detected section. If the problem is detected again after 3 days, it will be moved to the In Progress section.
Add an event_id parameter to your AddToCart event in your server payload. You can use the Payload Helper tool on the Facebook for Developers website to confirm that your payload has been configured correctly.
