hb_uuid is set to undefined when running video ads

[amanjain]

We had setup video ads using the steps given in:
http://prebid.org/dev-docs/examples/jw-selfhost-example.html and
http://prebid.org/dev-docs/show-video-with-a-dfp-video-tag.html and
http://prebid.org/examples/video/jwPlayerPrebid.html

hb_uuid of cust_params is set as undefined

and hence we are getting 400 error. Any insights?

Any reactions to this? I'm having the same issue

[dbemiller]

did you set the config to use the cache?

pbjs.setConfig({
  /* Or whatever your preferred video cache URL is */
  cache: {
    url: 'https://prebid.adnxs.com/pbc/v1/cache'
  }
});

If you missed that step, there would be no UUID available to fetch the VAST.

yeah above ^ is most likely the cause. Sorry for the confusion, I don't think we documented this change very well. We should probably also warn in this case in the console.

@mkendall07 I would add it near buildVideoUrl and setConfig sections.
