VMAP-1.0-adtaguri-empty

`<AdTagURI>` must contain a URI referencing an ad response

ErrorVMAPIAB VMAP 1.0.1 §2.3.2VMAP 1.0 (all VMAP documents)

Short answer

An <AdTagURI> element with no content gives the player no URL to fetch for the ad break. A non-empty URI is required.

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. VMAP rules validate the ad break schedule envelope. Malformed break timing, wrong namespace declarations, or invalid AdSource content prevent players from resolving any of the ads in the playlist. Affected scope: VMAP 1.0 (all VMAP documents).
