Events are being sent through both pixel and server to Meta. The events are not being deduplicated

Purchase, ViewContent, AddToCart, InitiateCheckout, PageView Event, events are being sent through both pixel and server. The events are not being deduplicated because an event_id parameter hasn't been added. Without an event_id, your Purchase events will be counted twice because they can't be deduplicated. This may cause issues with the attribution of your ad campaigns.
