Querying a document collection does not seem to return non-XML files

[grantcv1]

I'm running the Alpha 3 Docker instance.

I'm finding that I can't see the PDF files I have installed alongside my XML documents.

This had worked fine with eXist-db and I've changed nothing other that switch to the FusionDB instance.

My simplified xquery is:

xquery version "3.1"; declare namespace d="DAV:"; for $doc in collection('/repository/grantcv1')   return (     let $fileURI := base-uri($doc)     return <d:response xmlns:d="DAV:">       <d:href>{$fileURI}</d:href>     </d:response>   )   I get all the XML files, but nothing else. I used to get the complete list of files in the folder.
