Azure Server Farm Not Found - powershell

Question

I am trying to create an azure website via a powershell script. The hosting plan has already been create, I simply wish to add a new website to it.
The script I'm using is this:
Switch-AzureMode AzureResourceManager
$targetServicePlan = Get-AzureResource -Name my-serviceplan -OutputObjectFormat New
New-AzureResource -Name MyTestSite -Location "West Europe" `
-ResourceGroupName Default-Web-WestEurope `
-ResourceType 'Microsoft.Web/sites' `
-PropertyObject #{"name" = "MyTestSite"; "ServerFarmId" = $targetServicePlan.ResourceId } `
-OutputObjectFormat New
The server farm ($targetServicePlan) has a resource id, so I'm assuming that it exists (there is also a hosting plan in the azure portal with this name). Yet when I try to create the website I get the error: "Server farm with name my-serviceplan not found."
The full error is:
New-AzureResource : {"Code":"NotFound","Message":"Server farm with name my-serviceplan not found.","Target":null,"Details":[{"Message":"Server farm with name
my-serviceplan not found."},{"Code":"NotFound"},{"ErrorEntity":{"Code":"NotFound","Message":"Server farm with name my-serviceplan not
found.","ExtendedCode":"11001","MessageTemplate":"Server farm with name {0} not found.","Parameters":["my-serviceplan"],"InnerErrors":null}}],"Innererror":null}

What am I missing?

Answer 1

Is your $targetServicePlan in 'West Europe'? If not that could be the reason for that not-so-helpful error.
