ACTIVATION_TIMESTAMP_INVALID
- HTTP status
- 400
- Details payload
{ activationTs: string, firstExposureTs: string, message: "activation must occur after first exposure" }
Cause
An activation timestamp was placed at or before the first Exposure it would filter, which would silently drop the Entities the Run already measured.
Fix
Move the activation timestamp after details.firstExposureTs. An activation point earlier than the first Exposure cannot be honored without discarding measured data, so the platform refuses it rather than quietly truncating the analysis window.
