prebid - Prebid S2S (Java) 测试广告未展示

Question

我正在尝试在我自己的 AWS 服务器上实施 Prebid S2S (Java) 标头投标，下面是客户端代码（用于测试目的的课程不是真正的标头投标）：

var googletag = googletag || {};
        googletag.cmd = googletag.cmd || [];
        googletag.cmd.push(function () {
            googletag.pubads().disableInitialLoad();
        });

        var pbjs = pbjs || {};
        pbjs.que = pbjs.que || [];

        var sizes = [
            [300, 250]
        ];
        var PREBID_TIMEOUT = 1000;
        var FAILSAFE_TIMEOUT = 3000;

        var adUnits = [{
            code: '/19968336/header-bid-tag-2',
            mediaTypes: {
                banner: {
                    sizes: sizes
                }
            },
            bids: [{
                bidder: 'appnexus',
                params: {
                    placementId: 13144370
                }
            }]
        }];

        pbjs.que.push(function () {
            pbjs.setConfig({
                debug: true,
                s2sConfig: {
                    adapter: 'prebidServer',
                    endpoint: "http://openbidding-env.eba-gxjapuw9.us-west-2.elasticbeanstalk.com/openrtb2/auction",
                   // syncEndpoint: syncEndpoint,
                    enabled: true,
                    accountId: '1', // replace this with your account id
                    bidders: ['appnexus']
                 
                    // timeout: 3000

                }
            });

            pbjs.addAdUnits(adUnits);

            pbjs.requestBids({
                bidsBackHandler: initAdserver,
                timeout: PREBID_TIMEOUT
            });
        });
        function initAdserver() {
            if (pbjs.initAdserverSet) return;
            pbjs.initAdserverSet = true;
            googletag.cmd.push(function () {
                pbjs.setTargetingForGPTAsync && pbjs.setTargetingForGPTAsync();
                googletag.pubads().refresh();
            });
        }

        setTimeout(function () {
            initAdserver();
        }, FAILSAFE_TIMEOUT);

        $(document).ready(function () {


        });

        googletag.cmd.push(function () {
            googletag.defineSlot('/19968336/header-bid-tag-2', sizes, 'div-1')
                    .addService(googletag.pubads());
            googletag.pubads().enableSingleRequest();
            googletag.enableServices();
        });

当我禁用 s2s 时代码工作正常，但是当我启用它时，显示的是谷歌默认测试广告“所有投标人花费了太长时间”而不是 Prebid 测试广告，我不知道我的代码有什么问题。服务器端是否需要进行任何更改？

下面是邮递员的响应，这意味着服务器正在运行并且工作正常。
