Dear support,

I need your help with the below issue.

I was trying to register Azure CDN as an app using PowerShell and I found this article "https://github.com/MicrosoftDocs/azure-docs/commit/080f0d88908a563b2c47759ac2b4facd38ec487b" and I tried to follow the mentioned steps but I got below error when I run "New-AzureRmADServicePrincipal -ApplicationId "205478c0-bd83-4e1b-a9d6-db63a3e1e1c8"

The Error is:

New-AzureRmADServicePrincipal : Object reference not set to an instance of an object. At line:1 char:1 + New-AzureRmADServicePrincipal -ApplicationId 205478c0-bd83-4e1b-a9d6- ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : CloseError: (:) [New-AzureRmADServicePrincipal], NullReferenceException + FullyQualifiedErrorId : Microsoft.Azure.Commands.ActiveDirectory.NewAzureADServicePrincipalCommand

Attached screenshot for more info.

    @Nicen
    It looks like you might have one too many quotes within your PS command, which could've caused the Application ID to not actually reference an object or App in this case. Can you try running the below command. You can do so using Azure PowerShell on your desktop or Azure Cloud Shell within the Portal. Keep in mind that if you're using your desktop you'll need AzureRM modules unless you'd like to use the Az commands to create a service principle.

    New-AzureRmADServicePrincipal -ApplicationId "205478c0-bd83-4e1b-a9d6-db63a3e1e1c8"

    If you have any other questions please let me know.
    Thank you for your time!
