Description

Hi,

Following PS script is run on Azure DevOps using Microsoft-hosted agents (windows-2025).
Basically I'm trying to send a message to an SA queue using PS Az module, but I'm getting this error:

##[error]You cannot call a method on a null-valued expression.

This is the PS script, line in bold is the one throwing the error

$azureStorageContext = New-AzStorageContext -StorageAccountName $(StorageAccountName) -StorageAccountKey $(StorageAccountKey)

$queue = Get-AzStorageQueue -Name $(QueueName) -Context $azureStorageContext

$queueItem = "my message"
$queueMessage = New-Object -TypeName Microsoft.Azure.Storage.Queue.CloudQueueMessage -ArgumentList "$queueItem"
$queue.CloudQueue.AddMessageAsync($queueMessage)

Could you tell me what I'm missing to make it work?

Issue script & Debug output

#Script

$azureStorageContext = New-AzStorageContext -StorageAccountName $(StorageAccountName) -StorageAccountKey $(StorageAccountKey)

$queue = Get-AzStorageQueue -Name $(QueueName) -Context $azureStorageContext

$queueItem = "my message"
$queueMessage = New-Object -TypeName Microsoft.Azure.Storage.Queue.CloudQueueMessage -ArgumentList "$queueItem"
$queue.CloudQueue.AddMessageAsync($queueMessage)


#Output
