@codewiz14 I'm looking at this and things generally look good, but your endpoint is refusing test connections. We need 100% fill sample bid params so we can see bids to verify adapters and so that publishers can use it to verify their own builds and integrations work.

This is what I'm seeing:

Access to XMLHttpRequest at 'https://central.mall.tv/bid' from origin 'http://127.0.0.1:9999' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
VM378:1 POST https://central.mall.tv/bid net::ERR_FAILED

I've tried both the params here and in your doc PR and neither is returning bids.

Hi @GLStephen, it was configured to work only for localhost:9999, we just updated the CORS policy to allow on 127.0.01:9999 as well.
Everything should work with params in our docs for both adapters.

@codewiz14 the gjirafa bidder looks good, but the malltv bidder is receiving an error here:

  if (!hasValidKeys()) {
    logError(errorMessage(`Bidder ${bid.bidderCode} is missing required params. Check http://prebid.org/dev-docs/bidder-adapter-1.html for list of params.`));
    return false;
  }

The error is:

ERROR: Invalid bid from malltv. Ignoring bid: Bidder malltv is missing required params. Check http://prebid.org/dev-docs/bidder-adapter-1.html for list of params.

I suspect a required parameter may have changed in V4.

@GLStephen the issue was on interpret response when there is no bid, so we just updated interpretResponse to return an empty array when there is no bid.

@codewiz14 I missed the window for the release today, but this will be in the next release
