"Encountered unsupported property Type" Error in Cloudformation with Route53

When attempting to build a AWS::Route53::RecordSet using cloudformation, I get "Encountered unsupported property Type" error. I am assuming this means it does not recognize "Type": "A" in my JSON. However, that is a valid property of AWS::Route53::RecordSet and is even in the example AWS gives in the documentation. (I understand this is for RecordSetGroup, but the example at the bottom builds a RecordSet).

I have also tried copying and pasting the exact example Amazon gives and subbing out their values for mine. Still no luck.

Here is my code: 

"DNS" : {
      "Type": "AWS::Route53::RecordSet",
      "Properties": {
        "HostedZoneName": {
          "Ref": "HostedZoneName"
        },
        "Comment": "DNS name for my instance.",
        "Name": {
          "Fn::Join": [
            "",
            [
              {
                "Ref": "ComponentDNSName"
              },
              {
                "Ref": "HostedZoneName"
              }
            ]
          ]
        },
        "Type": "A",
        "TTL": "900",
        "ResourceRecords": [
          {
            "Fn::GetAtt": [
              {
                "Fn::GetAtt": [
                  "Ec2Instance",
                  "PrivateIp"
                ]
              }
            ]
          }
        ]
      }
    }

I thought it might be brackets in the wrong places, but I have double checked that and other resources in my stack (alarms, EC2Instance) build fine.

Thank you for any help.

Are you sure it's complaining about "Type" in this part of the code and not somewhere else? Have you tried removing this entire resource? – kichik
I have tried that. If I remove the DNS entry, the rest builds fine. – Brandon
Why the Fn::GetAtt inside another Fn::GetAtt? – jogold

The issue is with ResourceRecords I think. Replace the current one with 

   "ResourceRecords": [
      {
        "Fn::GetAtt": [
            "Ec2Instance",
            "PrivateIp"
        ]
      }
    ]

If you have multiple inputs to be added to ResourceRecords, it will become

   "ResourceRecords": [
      {
        "Fn::GetAtt": [
            "name1",
            "resource1"
        ]
      },
      {
        "Fn::GetAtt": [
            "name2",
            "resource2"
        ]
      }
    ]

Hope this helps.
