New-AzSqlDatabaseImport Cannot bind argument to parameter 'OperationStatusLink' because it is null

When attempting to deploy databases to Azure SQL using PowerShell with the New-AzSqlDatabaseImport command I am receiving the following error:

New-AzSqlDatabaseImport : An unexpected error occured while processing the request. Tracking ID: 'mytrackingid'

What is odd is that I have run this script over a 100 times on other VMs and am wondering if something has changed or is off in this VM being able to grab the desired bacpac file from blob storage.

I have already checked the Lifecycle of the blob storage and there is nothing listed on that page. The blob and containers exist.

I have installed the Az and SQLServer modules and am able to connect to Azure using the Connect-AzAccount followed by setting my desired subscription by Set-AzContext -SubscriptionId

I have checked the NSGs and am able to open web pages from a browser on the VM I am running the following PowerShell from:

$importRequest = New-AzSqlDatabaseImport -ResourceGroupName "myresourcegroup" `
   -ServerName "5878956-sql" `
   -DatabaseName "mydatabase"`
   -DatabaseMaxSizeBytes "262144000" `
   -StorageKeyType "StorageAccessKey" `
   -StorageKey "mylongaccesskey" `
   -StorageUri "https://myblobs.blob.core.windows.net/mycontainer/mydatabase.bacpac" `
   -Edition "Standard" `
   -ServiceObjectiveName "S1" `
   -AdministratorLogin "azuresqladmin" `
   -AdministratorLoginPassword $(ConvertTo-SecureString -String "mypassword" -AsPlainText -Force)

# Check import status and wait for the import to complete
$importStatus = Get-AzSqlDatabaseImportExportStatus -OperationStatusLink $importRequest.OperationStatusLink
[Console]::Write("Importing mydatabase")
while ($importStatus.Status -eq "InProgress")
{
    $importStatus = Get-AzSqlDatabaseImportExportStatus -OperationStatusLink $importRequest.OperationStatusLink
    [Console]::Write(".")
    Start-Sleep -s 10
}
[Console]::WriteLine("")
$importStatus

Update 1:

Testing today, I am able to import a database through the Azure Portal GUI but PowerShell does not work. I am able to download the blob/bacpac files via PowerShell but the importing with the New-AzSqlDatabaseImport is still failing.

In checking the Azure Portal Activity Log it is showing the following error, so we believe it is communicating with Azure SQL:

"subStatus": {
    "value": "InternalServerError",
    "localizedValue": "Internal Server Error (HTTP Status Code: 500)"
},
