Question

In a first/last computed trait I am capturing an event property, however, there are profiles that performed the event that do not have the trait computed.

Product

Twilio Segment

Environment

Segment Console

Answer

Computed Trait gets the property value of first/last event seen​, and not the last value of the property seen in any event. This means that if the first/last event seen for the profile does not have the property, the computed trait will be computed as null.
