openrtb.3.0.openrtb_root

What it means

OpenRTB 3.0 changes the structure around openrtb.

OpenRTB 3.0 introduced the Openrtb root object as the container for transport and payload metadata.

Why it matters

A structural shift changes where data lives, so a payload shaped for an earlier version does not map cleanly onto 3.0.

How to fix it

Reshape the payload to the 3.0 layout for openrtb.
