“New-AzureRmNetworkInterface : Cannot parse the request.” What is blocking this command in Azure?

Question

I'm trying to set up an architecture in azure with a script Powershell. But I have an unexpected error telling me that the request is : "ReasonPhrase: Bad Request"

My only documentation for this project is the microsoft doc. This is where I found this command and some exemple of script for creating a VM with powershell.

My real problem is that this cmdlet works when I use a script which create one VM in one run. But in this script I am looking to first create all network interfaces before hand and then merge them to their VM.

$LocationName = "West Europe"
$ResourceGroupName = "RGPackage01","RGLab01","RGFileStock01"

-Location $LocationName 
-AllocationMethod Dynamic

$NIC = New-AzureRmNetworkInterface 
-Name $NICName[0] 
-ResourceGroupName $ResourceGroupName[0] 
-Location $LocationName 
-SubnetId $Vnet.Subnets[0].Id 
-PublicIpAddressId $PIP.Id

This is now working, the issue was from the fact that an network interface need a subnet to be created. I didn't created subnet but only a virtual network. So I firts create the config of 4 subnet with New-AzureRmVirtualNetworkSubnetConfig and I link them to the virtual network when i created it New-AzureRmVirtualNetwork -Subnet.

Now In the command New-AzureRmNetworkInterface I can right in the argument -SubnetId $Vnet.Subnets[0].Id. It's going to look for the first subnet id in the virtual network.

That's it I edited my question including your solution, thank you for the help — Bruno SENELLART

$subnetid[1].Id is the id of virtual network, not the id of the subnet. The value of SubnetId should be something like

-SubnetId "/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/ResourceGroup1/providers/Microsoft.Network/virtualNetworks/VirtualNetwork1/subnets/Subnet1"

You missed /subnets/Subnet1.

You should use $subnetid[1].Subnets[0].Id as the value of SubnetId.
