Hi @Vinay_M_R 

Thanks for replying.  The docs link is the same as the link that I included in my original post - and it is where I am following the code examples from.  That example shows a pdf being read from a Volume - but are you saying I should not do this and should read directly from a Blob store instead? 🤔  I thought the Databricks position was that Volumes are the way forward?
