Start-AzureSqlDatabaseExport: Object reference not set to an instance of an object

I am trying to start an export of a SQL Azure database to a blob. However, after trying different approaches and searching the web I can't find a way to make it work. 

$exportRequest = Start-AzureSqlDatabaseExport -SqlConnectionContext $SqlContext -StorageContainer $Container -DatabaseName 'Users' -BlobName 'autobackupotest.bacpac' -Verbose -Debug

The line above results in: 

DEBUG: 2:05:14 PM - StartAzureSqlDatabaseExport begin processing with ParameterSet 'ByContainerObject'.
WARNING: Client Session Id: '111746f6-65c2-4ba1-b7c6-52a9171ee6-2016-03-28 08:15:58Z'

DEBUG: 2:05:19 PM - StartAzureSqlDatabaseExport end processing.

I verified the variables I use for this cmdlet and they are not null. Prior to that cmdlet I use the following code: 

Import-Module Azure 
Import-Module Azure.Storage

Get-AzureRmSubscription –SubscriptionName “Production” | Select-AzureRmSubscription

# Username for Azure SQL Database server
$ServerLogin = "username"

# Password for Azure SQL Database server
$serverPassword = ConvertTo-SecureString "abcd" -AsPlainText -Force


# Establish credentials for Azure SQL Database Server 
$ServerCredential = new-object System.Management.Automation.PSCredential($ServerLogin, $serverPassword) 

# Create connection context for Azure SQL Database server
$SqlContext = New-AzureSqlDatabaseServerContext -FullyQualifiedServerName “myspecialsqlserver.database.windows.net” -Credential $ServerCredential

$StorageContext = New-AzureStorageContext -StorageAccountName 'prodwad' -StorageAccountKey 'xxxxx'
$Container = Get-AzureStorageContainer -Name 'automateddbbackups' -Context $StorageContext

$exportRequest = Start-AzureSqlDatabaseExport -SqlConnectionContext $SqlContext -StorageContainer $Container -DatabaseName 'Users' -BlobName 'autobackupotest.bacpac' -Verbose -Debug

What could be wrong here? That exception message does not provide any detail.

I tested your code and it works fine on my side.

Run Login-AzureRmAccount to login before Get-AzureRmSubscription –SubscriptionName “Production” | Select-AzureRmSubscription, verify that the subscription Production exists in current tenant. And double check the username,password for SQL server, StorageAccount,StorageAccountKey,ContainerName are all correct.
