UniversalAdId extension requires an ID in element text or unknown

ErrorCTV Addendum 2024IAB CTV Addendum 2024 (July 2024)VAST 2.0 and later (all versions)

Short answer

UniversalAdId must contain an ID in element text. Use unknown for an unregistered ad. An empty element does not identify the creative.

Why this matters in production

This rule is usually a delivery blocker. Many players, SDKs, and ad servers will discard the response or skip the affected creative once this condition is hit. These rules validate supplied standardized payloads carried in legacy VAST extensions. Correct version and location handling preserves compatibility while checking ID registries, mezzanine assets, SIMID payloads and creative bindings. Optional addendum features remain optional. Affected scope: VAST 2.0 and later (all versions).
