Blank and Multiple Bids are passing in dfp Prev_scp

[gauravparashar12]

Implementation Issue :I have implemented prebid on my website with multiple partners But i have facing empty parameters and sometimes double bids for single slot .I have attached the screenshot

and I have implemented following code for prebid `var PREBID_TIMEOUT=1000;

function initAdserver() {
        if (pbjs.initAdserverSet) return;
        /*load GPT library here*/
        (function() {
            var gads = document.createElement('script');
            gads.async = true;
            gads.type = 'text/javascript';
            var useSSL = 'https:' == document.location.protocol;
            gads.src = (useSSL ? 'https:' : 'http:') +
                    '//www.googletagservices.com/tag/js/gpt.js';
            var node = document.getElementsByTagName('script')[0]; 
            node.parentNode.insertBefore(gads, node);
        })();
        pbjs.initAdserverSet = true; 
    };

        /*Load the Prebid Javascript Library Async. We recommend loading it immediately after
    the initAdserver() and setTimeout functions.*/
    (function() {
        var d = document, pbs = d.createElement('script'), pro = d.location.protocol;
        pbs.type = 'text/javascript';
        pbs.src = 'https://central.bhaskar.com/js_ads/ads/header-bidding/bhaskar/library/prebid.js';
        var target = document.getElementsByTagName('head')[0];
        target.insertBefore(pbs, target.firstChild);
    })();

    pbjs.que.push(function(){

        const customConfigObject = {
          "buckets" : [{
              "precision": 2, 
              "min" : 0.01,

Blank values are normal -- could be no-bids or timeouts.

Please post an example where there are two bids for a single slot?

[bretg]

If there's a problem, it may be related to the definition in bidderSettings of adserverTargeting and the issue reported https://github.com/prebid/Prebid.js/issues/1267

I recommend removing as much of the bidderSettings.adserverTargeting as possible. If you want to adjust bid values (like you're modifying hb_pb_criteo), try bidderSettings.bidCpmAdjustment rather than adserverTargeting.

Hello @bretg you can see in the screenshot

[bretg]

Please help us understand why you're setting sendStandardTargeting to false and overridding everything with what amounts to the standard targeting?

1) there are known bugs with overridding standard targets.

2) modifying bid CPM should be done with bidderSettings.bidCpmAdjustment

[manishdhiman]

we are using custom standard targeting that is why we have to do false, otherwise it can pass values into hb_pb, which we have not created values into dfp lineitem.

[bretg]

@manishdhiman - the only custom value I'm seeing in the code above is the CPM for criteo. My point is that if that's the only customization, it should be done with bidderSettings.bidCpmAdjustment.

Otherwise, if there are other customizations not shown above, then you'll need to wait for #1267.

[bretg]

@manishdhiman - did this work for you? I'm going to close this out. You're welcome to re-open with addtitional detail if needed.
