ERROR CODE / DUPLICATE_EVENT
The event was already received
An event with the same event_id already arrived for this website and environment, through the same route: from the browser or from a server. It was not counted again.
01
What is missing while this finding stands
None if it was a retry. If these were two different events with the same event_id, the second one is missing.
02
How to fix it
01
For a retry, no action is required.
02
If your system assigns the same event_id to different events, make it unique, for example from the kind of event and the order number.
