Bug description
Hi all,
Investigating hundreds of 404 errors in my ingress logs I found that apparently the preview icons in shared folders are to blame.
For logged-in users the previews show up correctly, whereas in an anonymous session via public share I get loads of 404 and afterwards a generic document icon displayed. Only the markdown files are rendered with a proper preview.
This is true for both, old shares as well as newly created shares.
Steps to reproduce
- Put files into a folder
- Create a public sharing link
- open the public sharing link in an anonymous browser session.
- see no previews/ incorrect icons.
Expected behavior
Logged-in and anonymous users should see identical previews/ icons for shared folders.
