amp-ad: OpenX Not passing DFP attributes, other than slot

[krcrawford]

Using <amp-ad type="openx">, data-dfp-* values other than data-dfp-slot are not passed to DoubleClick as documentation suggests:

OpenX Bidder

OpenX header bidding. Parameters noted in the Doubleclick amp-ad documentation can be forwarded to Doubleclick by the following rules:

Parameters like data-dfp-{name} will be converted to data-{name} and passed to Doubleclick

Load several consecutive ads with similar attributes, (six in my case)

<amp-ad width="728" height="90"
      type="openx"
      data-host="domain.openx.net"
      data-auid="12345"
      data-nc="56789-MySite"
      data-dfp-slot="/12345/dfp_zone"
      data-dfp-multi-size="970x91,960x91,728x90,900x71" // this being the suggested approach above
      json='{"dfp":{"targeting":{"sport":["rugby","cricket"]},"categoryExclusions":["health"],"tagForChildDirectedTreatment":1},"openx":{"customVars":{"marco":"polo","fates":["clothos","lachesis","atropos"]}}}'>
</amp-ad>

This seems to be a data validator issue where openx amp-ad is trying to validate the data intended for dfp, and thus fails in 3p:validateData.

Occurrence seems arbitrary.

@krcrawford are you a user of openx? can you report bug to openx? a temp fix might be removing this line, but just want to make sure openx is aware of this change.

From OpenX Sr.

There are known bugs with our AMP integration, and we have recently begun alpha testing a new solution.

Thanks, closing here since it's not a core AMP issue.
