openrtb.2.6-202409.eid.matching

What it means

OpenRTB 2.6-202409 introduced eid.inserter, eid.matcher, eid.mm, which openRTB 2.6-202409 added EID insertion, matcher, and match-method fields..

Why it matters

eid.inserter is only defined from 2.6-202409 onward. Used against an earlier version it is not valid, and a consumer below 2.6-202409 treats it as an unknown field.

How to fix it

Target OpenRTB 2.6-202409 or later when you send eid.inserter, 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 2.6-202409 to see whether this rule fires against your payload.
