title: @BlobInput is coming back null in Java Azure Function
body: <p>I'm trying to use the @BlobInput annotation in a Java Azure Function and the argument that i'm annotating does not get populated with the content of the blob i'm referencing.</p>
  
  <p>I believe it might have something to do with the "name" field of the BlobInput, but i'm a little unclear on what that's supposed to be populated with. According to the documentation <a href="https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob-trigger?tabs=java" rel="nofollow noreferrer">here</a>, it should be </p>
  
  <blockquote>
    <p>The name of the variable that represents the blob in function code</p>
  </blockquote>
  
  <p>But I'm very unclear on what exactly that means. Is there something i should be putting in my local.settings.json to get this thing to run the way i'm expecting it to?</p>
