Google Tag Manager未向Analytics发送电子商务数据

我通过GTM添加了下面的代码,当我进行测试购买时,我看到了数据层,但电子商务数据没有发送到analytics。我在成功页面的页面视图上启动了标记。

<script>
window.dataLayer = window.dataLayer || [];

var productArray = [];
   var x = document.getElementsByClassName("ved");
   var quantity = document.getElementsByClassName("qty-class");
   var sku = document.getElementsByClassName("productid");
   var price = document.getElementsByClassName("price-class");

        var y = x[0].innerHTML;
        var len=x.length;
    for(i=0; i < len; i++){
      var pO = {};
      pO.name = x[i].innerHTML;
      pO.quantity = parseInt(quantity[i].innerHTML);
      pO.price = parseInt(price[i].innerText);
      pO.sku = sku[i].innerHTML;
      pO.category = 'MyCategory';

      productArray.push(pO);
    };

   var revenue = document.getElementById("order-total").innerText;
   var ship = document.getElementById("shipping").innerText;
   var tid = document.getElementById("t_id").innerText;

dataLayer.push({
'transactionId': tid,
'transactionAffiliation': 'MyWebsite',
'referrer':{{ref}},
'transactionTotal': parseInt(revenue),
'transactionTax': 0,
'transactionShipping':parseInt(ship),
'transactionProducts': productArray,
'event':'transactioncomplete'
}); 

</script>
