Deduplicate events

Hi guys,
i’ve followed this guide from Stape’s team (attached below) step by step

to deduplicate events, but it seems that there’s some problem in passing event_id by the client, so deduplication doesn’t work properly.

Anyone faced the same issue?

Maybe do i have to create a custom dimension in GA4?

Let me know, thanks for you precious support.


It looks like the problem is that you did not add the Unique event id variable to the browser event. Point 4 of the guide.
