MVC DotNet 6 Upload Images to Azure Blob Storage and disk

I was stuck in the SavePicture method, in fileExtension both File and Filename is null and it returns the error System.NullReferenceException: 'Object reference not set to an instance of an object.'

Σε ευχαριστούμε πολύ για την καλή δουλειά σου!!!
