ActiveStorage::Attachment#download returns empty string

[manuelmeurer]

I'm trying to download an attachment but only get an empty string:

> file
#<ActiveStorage::Attachment:0x00005609c9fc6718> {
             :id => 23,
           :name => "files",
    :record_type => "ContractTemplate",
      :record_id => 1,
        :blob_id => 28,
     :created_at => Wed, 29 Jul 2020 15:18:43 CEST +02:00
}

[3] Uplink PROD(main)> file.download
  Cloudinary Storage (18.5ms) Downloaded file from key: abc
""

It only happens with this one file AFAIK and it's a docx file. Maybe that is the problem?

I can see it in the Cloudinary media console and download it from there without problems. Also, downloading via the ActiveStorage blob URL (https://my.app/rails/active_storage/blobs/eyJfcmFpbHMiOnsibWVzc2FnZSI6IkJBaHBJUT09IiwiZXhwIjpudWxsLCJwdXIiOiJibG9iX2lkIn19--765be73bbb13e3825e0c04cfc0d18c68cf05478d/my-file.docx) works without a problem too, so it really seems to be that #download method that is the problem.

@manuelmeurer We are looking into your request. And we will update once we are able to reproduce it on our end.

@d-mendoza Thanks! Let me know if I can do anything to help.

@manuelmeurer When I tried to download it, I get something like this:

Cloudinary Storage (138.0ms) Downloaded file from key: ypasifasuu5d5uz0dn1e5fzkwz5e => "\xFF\xD8\xFF\xE0\x00\x10JFIF\x00\x01\x01\x01\x00d\x00d\x00\x00\xFF\xDB\x00C\x00\x...

So it seems to be working. I wonder if you have something else that's conflicting with it or maybe the file is corrupted. Any change you also try it on another docx file?

@d-mendoza I have the same issue with .download link for PDF files.
