$resourceGroup = "WindowsServerUpgrades"
$location = "WestUS2"
$zone = "" 
$diskName = "WindowsServer2022UpgradeDisk"
$sku = "server2022Upgrade"
$publisher = "MicrosoftWindowsServer"
$offer = "WindowsServerUpgrade"
$managedDiskSKU = "Standard_LRS"
$Tags = 
@{"Application"="Test";`
"Owner"="User1";`
"Environment"="Development";}
$versions = Get-AzVMImage -PublisherName $publisher -Location $location -Offer $offer -Skus $sku | sort-object -Descending {[version] $_.Version	}
$latestString = $versions[0].Version
$image = Get-AzVMImage -Location $location `
                       -PublisherName $publisher `
                       -Offer $offer `

                       -Version $latestString
if (-not (Get-AzResourceGroup -Name $resourceGroup -ErrorAction SilentlyContinue)) {
    New-AzResourceGroup -Name $resourceGroup -Location $location    
}
if ($zone){
    $diskConfig = New-AzDiskConfig -SkuName $managedDiskSKU `
                                   -CreateOption FromImage `
                                   -Zone $zone `
                                   -Location $location
} else {
    $diskConfig = New-AzDiskConfig -SkuName $managedDiskSKU `
                                   -CreateOption FromImage `
                                   -Location $location
} 
Set-AzDiskImageReference -Disk $diskConfig -Id $image.Id -Lun 0
New-AzDisk -ResourceGroupName $resourceGroup `
           -DiskName $diskName `
           -Disk $diskConfig

Hi Glenn Maxwell, It seems like there is an issue with the data type of the $image.Id parameter. The Set-AzDiskImageReference cmdlet requires a string data type for the -Id parameter, but it seems like $image.Id is an object array.

You can try converting the $image.Id object array to a string using the -join operator. Here's an example:

Set-AzDiskImageReference -Disk $diskConfig -Id ($image.Id -join "") -Lun 0 -Verbose

This should convert the $image.Id object array to a string and pass it to the -Id parameter of the Set-AzDiskImageReference cmdlet.It seems like there is an issue with the data type of the $image.Id parameter.

@Glenn Maxwell You were missing below 3 lines of the code and also you declared the variable $Tags and initialized but you are not using that $Tags variable.

#use -Tag flag in New-AzDiskConfig command

$diskConfig = New-AzDiskConfig -SkuName $managedDiskSKU -CreateOption FromImage -Zone $zone -Location $location -Tag $Tags #Get the existing VM by name

$vm = Get-AzVM -ResourceGroupName $resourceGroup -Name $VMName

#Add the created disk to the VM

$vm = Add-AzVMDataDisk -VM $vm -Name $diskName -CreateOption Attach -ManagedDiskId $disk.Id -Lun 1

#Update the disk

Update-AzVM -ResourceGroupName $resourceGroup -VM $vm
