openrtb.2.6-202606.macro.auction_discount

What it means

OpenRTB 2.6-202606 introduced macro.${AUCTION_DISCOUNT_PCT}, macro.${AUCTION_DISCOUNT_CPM}, which openRTB 2.6-202606 added seller discount substitution macros and revised the ${AUCTION_PRICE} definition..

Why it matters

macro.${AUCTION_DISCOUNT_PCT} is only defined from 2.6-202606 onward. Used against an earlier version it is not valid, and a consumer below 2.6-202606 treats it as an unknown field.

How to fix it

Target OpenRTB 2.6-202606 or later when you send macro.${AUCTION_DISCOUNT_PCT}, and make sure the value matches the type and any enum the specification defines for it.
