Our platform uses the latest data point for testing a trigger.
If you don't have any data (for conversions, affiliates or customers) there won't be anything showing up.
Take this example...
If you set up a trigger to fire with the 'conversion created' event, 'a corresponding data point' in this case refers to a previously tracked conversion.
We will 'replay' this conversion event in order to test the trigger.
Note: Be sure to check first if the event has any existing data in the account, as that data could be the cause of the error.
