Send message to azure service bus with properties - powershell

Question

I am using the following powershell code to send a message to an Azure Service Bus Topic with a property set:
function Send-AzServiceBusMessage {
param(
[Parameter(Mandatory = $true)]
[string] $ResourceGroupName,
[Parameter(Mandatory = $true)]
[string] $NamespaceName,
[Parameter(Mandatory = $true)]
[string] $TopicName,
[Parameter(Mandatory = $false)]
[string] $PolicyName = 'RootManageSharedAccessKey',
[Parameter(Mandatory = $false)]
[string] $Property1
)
$message = [PSCustomObject] #{ "Body" = "Test message"; "Property1" = $Property1 }
$namespace = (Get-AzServiceBusNamespace -ResourceGroupName $ResourceGroupName -Name $namespacename).Name
$key = (Get-AzServiceBusKey -ResourceGroupName $ResourceGroupName -Namespace $namespacename -Name $PolicyName).PrimaryKey
$message.psobject.properties.Remove("Body")
$token = New-AzServiceBusSasToken -Namespace $namespace -Policy $PolicyName -Key $Key
#set up the parameters for the Invoke-WebRequest
$headers = #{ "Authorization" = "$token"; "Content-Type" = "application/atom+xml;type=entry;charset=utf-8" }
$uri = "https://$namespace.servicebus.windows.net/$TopicName/messages"
$headers.Add("BrokerProperties", $(ConvertTo-Json -InputObject $Message -Compress))
$result = Invoke-WebRequest -Uri $uri -Headers $headers -Method Post -Body $body
if ($result.StatusCode -ne 201) {
$result
}
I have a rule set up on a topic subscription such that:
Property1 in ('somevalue')
However, if I set up a catch all subscription with no rules, I can see the message is being received by that and not by the subscription with the rule. So my question is how do I send messages with properties set using powershell. Similar to this in C#:
var message = new BrokeredMessage { MessageId = Guid.NewGuid().ToString()};
message.Properties["Property1"] = "somevalue";

Answer 1

Based on the documentation it looks like you have to nest your custom properties in a Properties member:
$headers.Add("BrokerProperties", $(ConvertTo-Json -InputObject #{ Properties = $message } -Compress))

Answer 2

The solution was as above with the following modifications:
$message = [PSCustomObject] #{ "Body" = "Test message" }
$headers = #{ "Authorization" = "$token"; "Content-Type" = "application/atom+xml;type=entry;charset=utf-8"; "Property1" = $Property1 }
$headers.Add("BrokerProperties", $(ConvertTo-Json -InputObject $Message -Compress))
