openrtb.2.6.macro.min_to_win

What it means

OpenRTB 2.6-202204 introduced macro.${AUCTION_MIN_TO_WIN}, which openRTB 2.6 added the AUCTION_MIN_TO_WIN substitution macro..

Why it matters

macro.${AUCTION_MIN_TO_WIN} is only defined from 2.6-202204 onward. Used against an earlier version it is not valid, and a consumer below 2.6-202204 treats it as an unknown field.

How to fix it

Target OpenRTB 2.6-202204 or later when you send macro.${AUCTION_MIN_TO_WIN}, 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 2.6-202204 to see whether this rule fires against your payload.
