title: Directory has blank values while the file is listed in internal stage [Snowflake preview feature to support unstructured data]
body: <p>I am trying to generate key value pairs from the unstructured pdf file which is currently a preview feature. I have been able to create an internal stage and can see the file by using ls command. However, when I do a select * from directory(@), it's value is blank
  Note: I have enabled the directory = true while creating the internal stage</p>
