openrtb.2.3.imp.native.request

What it means

OpenRTB 2.3 introduced imp.native.request, which openRTB 2.3 added the native request payload for declaring required assets and fields..

Why it matters

imp.native.request is only defined from 2.3 onward. Used against an earlier version it is not valid, and a consumer below 2.3 treats it as an unknown field.

How to fix it

Target OpenRTB 2.3 or later when you send imp.native.request, 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 2.3 to see whether this rule fires against your payload.
