New-AzVM : Cannot parse the request.

When I try to execute your script, I also get the same error as below.

The error you are encountering is due to passing an invalid NIC ID

To resolve the issue, ensure that you pass the valid NIC ID under the command Add-AzVMNetworkInterface -VM $vm -Id. If there is no NIC, create a new one and attach it to the VM.

Here is the updated PowerShell Script to create a VM

    Connect-AzAccount
    
    $cred = Get-Credential
    
    $vnet = Get-AzVirtualNetwork -Name "myresource-vnet" -ResourceGroupName "myresource"
    
    $subnet = Get-AzVirtualNetworkSubnetConfig -Name "default" -VirtualNetwork $vnet
    
    $nic = New-AzNetworkInterface -Name "MyNIC" -ResourceGroupName "Prod-IT" -Location "EastUS" -Subnet $subnet
    
    $vm = New-AzVMConfig -VMName "MyVirtualVM" -VMSize "Standard_D1"
    
    $vm = Set-AzVMOperatingSystem -VM $vm -Windows -ComputerName "MyVM" -Credential $cred -ProvisionVMAgent -EnableAutoUpdate
    
    $vm = Set-AzVMSourceImage -VM $vm -PublisherName "MicrosoftWindowsServer" -Offer "WindowsServer" -Skus "2016-Datacenter" -Version "latest"
    
    $vm = Set-AzVMOSDisk -VM $vm -Name "MyOSDisk" -DiskSizeInGB 128 -CreateOption FromImage -Caching ReadWrite
    
    $vm = Add-AzVMNetworkInterface -VM $vm -Id $nic.Id
    
    New-AzVM -ResourceGroupName "Prod-IT" -Location "EastUS" -VM $vm

Output:

After running the PowerShell script, the VM has been created successfully.
