Request Body

{

    "properties": {
        "notes": "Some notes about this Virtual Machine.",
        "osType": "Windows",
        "size": "Standard_B1ms",

        "disallowPublicIpAddress": true,
        "galleryImageReference": {
            "offer": "SQL2017-WS2016",
            "publisher": "MicrosoftSQLServer",

            "sharedPublicIpAddressConfiguration": {
                "inboundNatRules": []
            }
        },
        "allowClaim": true,
        "storageType": "Standard"
    },
    "tags": {}
}

It's a asynchronous operation, through querying the Operation API, we get below failure message:

{
    "status": "Failed",
    "error": {
        "code": "TooManyPortsRequested",
        "message": "A virtual machine cannot expose more than 150 ports, but 0 ports were requested."
    }
}

Why it's failing here?
