openrtb.2.6-202303.imp.video.plcmt

What it means

OpenRTB 2.6-202303 introduced imp.video.plcmt, which openRTB 2.6-202303 added plcmt for modern video placement semantics..

Why it matters

imp.video.plcmt is only defined from 2.6-202303 onward. Used against an earlier version it is not valid, and a consumer below 2.6-202303 treats it as an unknown field.

How to fix it

Target OpenRTB 2.6-202303 or later when you send imp.video.plcmt, and make sure the value matches the type and any enum the specification defines for it.

Paste your bid request into the tester and select OpenRTB 2.6-202303 to see whether this rule fires against your payload.
