Error assigning bid key-values since 7.20.0

[reelcitizen]

Type of issue

Bug

Description

Since version 7.20.0 I get the below error when Prebid tries to assign bid key-values to ad units...

Exception in queued GPT command TypeError: e.getStatusCode is not a function

Steps to reproduce

In my script I'm using Prebid like this so it works in parallel with other header bidders... the prebid_units are defined by their DOM element ID and not their GAM ad unit ID.

pbjs.requestBids({
      adUnits: prebid_units,
      bidsBackHandler: () => {
        googletag.cmd.push(() => {
          pbjs.setTargetingForGPTAsync();
          requestManager.prebid = true;
          biddersBack();
        });
      },
      timeout: this.biddingTimeout,
});

With running Prebid 7.20.0 or higher I then get the following in the PBJS debug console...

Exception in queued GPT command TypeError: e.getStatusCode is not a function

This means the bidder key-values are not assigned to each GAM ad unit.

I assume it's related to this change: #9013

Expected results

Key-values are added to each ad unit on the page/

Actual results

Platform details

Prebid 7.20.0, client-side.

Other information

Problem since #9013

@reelcitizen, would you be able to provide a test page, or more of your pbjs setup (adunits and setConfig)? I am not able to reproduce and I suspect the issue is caused by some module interaction that I'm not currently able to find.

To clarify, what that stack trace tells me is that some of the bids that you're left with at the end of the auction are not "proper" bids - they don't have the properties a Prebid bid is supposed to have. We could change it so that the error goes away but you'd still be left with bids that are coming from somewhere unexpected.

Hi, thanks for taking a look. I've stripped out everything from the Prebid config and still get the error. I then tried adding/removing bidders but it didn't seem to be just one causing the problem. It seemed more about the number of bidders I was using.

With 8 bidders it seemed to work, more than that I started getting problems?

The ad config looks like this:

{
            code: "/43340684/RPS_STICKY_LB",
            mediaTypes: { banner: { sizes: [[320, 50]] } },
            bids: [
                { bidder: "rubicon", params: { accountId: "16622", siteId: "326086", zoneId: "1695086", sizes: [43] } },
                { bidder: "pubmatic", params: { publisherId: "159481", adSlot: "2969788" } },
                { bidder: "ix", params: { siteId: "545961", size: [320, 50] } },
                { bidder: "teads", params: { pageId: 127011, placementId: 138666 } },
                { bidder: "medianet", params: { cid: "8CUSVGW2K", crid: "131851077" } },
                { bidder: "sharethrough", params: { pkey: "4gSvFjPk3URipXomD5Y7r14X" } },
                { bidder: "amx", params: { tagId: "Z2FtZXItbmV0d29yay5uZXQ" } },
                { bidder: "onetag", params: { pubId: "75847b43ef0b8c2" } },
                { bidder: "criteo", params: { networkId: 11384 } },
                { bidder: 'yieldmo', params: { placementId: '3053840090234036317' } },
            ],
        }

@reelcitizen, do you have a live page with that config, even if it's running an earlier version of Prebid? I can try to redirect it to 7.20 on my end. Unfortunately I am still not able to reproduce.

[reelcitizen]

It would be on a site like https://www.rockpapershotgun.com

[dgirardi]

Still unable to reproduce :(

Here are some console dumps from my attempts... I am redirecting static/src/vendor/prebid/prebid7.7.0.js to a local version of Prebid that is built with

• version 7.20.0 and modules=fpdModule,openxBidAdapter,rubiconBidAdapter,appnexusBidAdapter,tripleliftBidAdapter,pubmaticBidAdapter,ixBidAdapter,teadsBidAdapter,medianetBidAdapter,sharethroughBidAdapter,amxBidAdapter,onetagBidAdapter,yahoosspBidAdapter,criteoBidAdapter,consentManagement,currency,enrichmentFpdModule,priceFloors,sharedIdSystem,id5IdSystem,userId,rtdModule,permutiveRtdProvider,yieldmoBidAdapter:

  www.rockpapershotgun.com-7.20.0-allModules.log

• tip of master (version 7.26.0-pre), all modules:
  www.rockpapershotgun.com-master.log

Everything seems to work as intended; there are new "bid rejected" warnings coming from #9013:

But no issues when setting targeting:

At this point I'm afraid I need you to set up a complete page that can reproduce the issue. Sorry!

[reelcitizen]

Hi, can you see if you get the error on this page please?
https://www.dicebreaker.com/games/magic-the-gathering-game/feature/magic-the-gathering-the-brothers-war-impressions

It seems to be about the number of bidders, if I take some away I can clear the error.

This is also my Prebid modules...

  "rubiconBidAdapter",

I think I tracked this down to an extension called AdWizard which monitors ad requests on the page... weird it was causing GPT errors though, it must not recognise the new bid values.

I appreciate the help here, closing the issue.

@reelcitizen, be aware that 7.20 has this issue - which was rejecting some bids in my log dumps above. You may want to skip to 7.22 to pull in the fix.
