openrtb.2.6.user_agent_brandversion

What it means

OpenRTB 2.6-202204 introduced device.sua, brandversion, which openRTB 2.6 added structured user-agent and brand-version objects..

Why it matters

device.sua 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 device.sua, 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.
