config.json error - Expecting ',', ']', got 'EOF' - when adding config parameters

[jimiamoore]

Here's my existing config. Which passes the jsonlint.com test.

{ "bridge": { "name": "Homebridge", "username": "CC:22:3D:E3:CE:30", "port": 51826, "pin": "031-45-154" },

    "platforms": [{
            "platform": "SmartThings",
            "name": "SmartThings",
            "app_url": "https://graph-na02-useast1.api.smartthings.com:443/api/smartapps/installations/",
            "app_id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
            "access_token": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
            },
            {
            "platform": "Hue",
            "users": {
      "001788FFFExxxxxx": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
      "001788FFFEyyyyyy": "yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy"
            },
            "lights": true
            },
            {
            "platform": "HarmonyHub",
            "name": "Harmony Hub"
            },
            {
            "platform": "TplinkLightbulb"
            }
    ]

}

And here is my best attempt at incorporating the amazondash config into my file. But I keep getting error's from jsonlint.com

{ "bridge": { "name": "Homebridge", "username": "CC:22:3D:E3:CE:30", "port": 51826, "pin": "031-45-154" },

    "platforms": [{
            "platform": "SmartThings",
            "name": "SmartThings",
            "app_url": "https://graph-na02-useast1.api.smartthings.com:443/api/smartapps/installations/",
            "app_id": "c01b355b-f290-4034-9962-8f5648b86c5a",
            "access_token": "bdd22628-5394-4558-9183-c27edac8eaa2"
            },
            {
            "platform": "Hue",
            "users": {
      "001788FFFExxxxxx": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
      "001788FFFEyyyyyy": "yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy"
            },
            "lights": true
            },
            {
            "platform": "HarmonyHub",
            "name": "Harmony Hub"
            },
            {
            "platform": "TplinkLightbulb"
            },
            {
            "platform": "AmazonDash",
            "buttons": [{
                    "name": "Dash Blue",
                    "mac": "74:c2:46:0a:f9:3f"
                },
                {
                    "name": "Dash Orange",
                    "mac": "10:ae:60:4d:6a:0b"
            }
    ]

}

I am specifically getting this error (Expecting ',', ']', got 'EOF') on the last line. I just can't seem to figure out how to correct this issue. Any help you can offer would be most appreciated.
