nbr 1: Technical Error

What it means

An internal failure on the bidder side (timeout, crash, dependency down).

A bidder returns nbr on an otherwise empty BidResponse to say why it is not bidding, instead of (or alongside) an HTTP 204. Code 1 is technical error.

What to do about it

These codes mean the bidder could not process the request at all. If you are the seller receiving them, first validate the requests you send: a request that fails a bidder's parser produces exactly this family. If you are the bidder emitting them, your own logs, not the exchange's, hold the cause.
