Required native request asset is missing from the response

openrtb.native.asset.required_missingerrorRequest/response pair

The native request marked an asset required, and the bid's adm does not return that id.

What it means

With the originating request supplied, each request asset with required=1 must appear in the native response assets under the same id.

Why it matters

A required title or main image that never comes back is an incomplete native ad. Publishers reject it; some exchanges do not even render.

How to fix it

Return every required request asset id. Optional assets may be omitted.

Example that trips it

{ "request": { "native": { "request": "{\"assets\":[{\"id\":1,\"required\":1,\"title\":{\"len\":90}}]}" } }, "adm": "{\"link\":{\"url\":\"https://ex\"},\"assets\":[]}" }

Pair validation with --request. Asset 1 is required and absent from adm.

Check your payload

Paste a bid request or response into the tester to see whether this code fires against it, or gate on the id in CI with the CLI: the id is stable, wording is not.
