關鍵問題與Universal Analytics跟蹤的交易時Universal Analytics跟蹤交易時

谷歌標籤助理報告2個嚴重錯誤：關鍵問題與Universal Analytics跟蹤的交易時Universal Analytics跟蹤交易時

Error: Unknown method name: 'addTransaction'
Error: Missing 1 required parameter(s) for method 'send'.

交易報告在谷歌分析，但我很擔心這樣的錯誤。這裏是我的報告代碼：

<script> 

(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){ 
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o), 
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m) 
})(window,document,'script','//www.google-analytics.com/analytics.js','ga'); 

ga('create', 'UA-XXXXXXXX-1', { 
    'clientId': 'XXX' 
}); 

    ga('require', 'ecommerce', 'ecommerce.js'); 

    ga('ecommerce:addTransaction', { 
    'id': '5', 
    'affiliation': 'xxx', 
    'revenue': '0', // revenue is 0 because discount coupon was applied 
    'shipping': '15', 
    'currency': 'CHF' 
    }); 

    ga('ecommerce:addItem', { 
    'id': '5', 
    'name': 'XXX', 
    'sku': '3387', 
    'price': '35.80', 
    'quantity': '1' 
    }); 

    ga('ecommerce:send'); 

ga('send', 'pageview'); 
</script>
