[Bug]: Download complete but failed to create library item

[mark-monteiro]

What was the Problem?

I am unable to download audiobook library items to a custom folder location on my phone's SD card. The download completes successfully, but I get the error 'Download complete but failed to create library item'. It's worth noting that the folder hierarchy for the author/books is created on the file system, and the cover image for the book is also added successfully. However, none of the audio files are added to the filesystem. There is more than enough space on the SD card (almost 100GB free).

NOTE: This ONLY applied to audiobooks. I am able to download and view e-book files successfully without issues

Steps to Reproduce the Issue

1. Create new custom download location
2. Download book to selected location
3. See error described above

What was Expected?

Audio files should download without error

When I navigate to the cover download URL in a browser I get the cover image displayed. When I do it for the audio download URL I get

Cannot GET /api/items/li_u2crysmram6n5tt0ya/file/9436100778983439428/download

It looks like this might be a server error not app.
