Google跟踪代码管理器/增强型电子商务-浏览量代码数据层推送不起作用

Question

在一个网站上，我已经使用dataLayer成功地与GTM集成了增强型电子商务，并且所有标签均处于触发状态，数据正按预期方式传递到Google Analytics（分析）。但是，在另一个克隆的网站上，我也以完全相同的方式设置了GTM / GA，但是dataLayer推送并未发送产品详细信息视图或产品列表印象。

我使用GTM中的基本页面视图标签在GA视图中启用了增强型电子商务功能，该标签的配置方式与工作网站完全相同，如下所示：

，然后推入脚本底部的dataLayer对象：

    dataLayer.push({
        'ecommerce': {
            'currencyCode': 'GBP',
            'impressions': gtmProducts
        }
    });

在Google Analytics Debugger v2.7中，我看到以下输出-没有在页面视图上传输产品印象！

                         _                          _       _   _

但是，如果我修改此推送代码以在自定义EEproductListingsUpdate事件代码上触发，如下所示：

    dataLayer.push({
        'event': 'EEproductListingsUpdate',
        'ecommerce': {
            'currencyCode': 'GBP',
            'impressions': gtmProducts
        }
    });

具有以下标记配置：

然后我在GA调试器中看到以下命令：

Running command: ga("gtm3.send", {hitType: "event", eventCategory: "eCommerce", eventAction: "Product Listings Update", eventLabel: undefined, eventValue: undefined})

所有展示都已发送完毕...为什么当dataLayer.push()出现在另一个网站上时，页面浏览量标记无法发送展示吗？在GA / GTM面板中，无论是代码方式还是配置方式，我应该在哪里找到答案？一切都一样？
