Amazon web services 分析参数“--更改批处理”时出错：JSON+路由53 DNS记录集更新无效

当我试图执行下面的代码时，我得到了这个错误。我是否缺少json格式的任何内容

 ```
 Error parsing parameter '--change-batch': Invalid JSON: Expecting value: line 7 column 14 (char 160)
JSON received: {
      "Comment":"To update private dns name recordset",
      "Changes":[
        {
          "Action":"UPSERT",
          "ResourceRecordSet":{
            "Name":devdnstest.test.com.,
            "Type":,
            "TTL":300,
            "ResourceRecords":[
              {
                "Value":"10.0.0.2"
              }
            ]
          }
        }
      ]
 }

在这段代码中，我试图将私有托管区域记录集从10.0.0.1更新为10.0.0.2。 它在抱怨类型：$CNAME。但我不知道还有什么可以放在里面。 感谢您的投入

谢谢
