uuid is undefined in prebid cache

[Roffray]

Type of issue

Question

Description

I've taken the videojs demo page from the documentation to test our own adapter (vuble). The problem is, when the adapter sends back an ad for DFP to play, the uuid in prebid url cache is "undefined" : https://prebid.adnxs.com/pbc/v1/cache?uuid=undefined because the hb_uuid sent to DFP is undefined too.

Steps to reproduce

Go in this link : http://demo.vuble.tv/headerbidding/videojs.vuble.html?pbjs_debug=true wich is setup to call our adapter.

Test page

http://demo.vuble.tv/headerbidding/videojs.vuble.html?pbjs_debug=true

Expected results

Whenever the adapter sends back an to play, we should be able to get DFP to get the vast from prebid cache.

Actual results

The hb_uuid sent to DFP is undefined, therefore the prebid cache url set up in DFP is not able to get the vast.

Platform details

I'm testing on Chrome 65.0.3325.146, with the latest prebid version (created with gulp serve).

Am I doing anything wrong or missing anything here ?

Thank you, Geoffray

You'll have the same issue here with this time the appnexus bidder : http://demo.vuble.tv/headerbidding/videojs.html.

Hi @Roffray, for the second example page with the appnexus bidder, you should be able to get a uuid by setting

pbjs.setConfig({ 
  cache: { url: 'https://prebid.adnxs.com/pbc/v1/cache' },
});

and for vuble, it looks like a uuid isn't getting set because the vuble bid response object doesn't contain a mediaType field set to 'video' (docs link). If you add that locally and it works out please submit a PR and we'll merge it
