What happened?

The audiobooks do not appear:
Error in logs:
[AudioFileScanner] Invalid data found when processing input ...
[Audible] ASIN search error [AxiosError: Request failed with status code 500] ...
[AudioFileScanner] SyntaxError: Expected property name or '}' in JSON at position 2 :...

This does not happen with all books

And these do not reappear on forced library re-scan

What did you expect to happen?

Audiobook should be visible in libraries

Steps to reproduce the issue

But when the above errors occur these disappear for all time.
The audio files are not corrupted

v2.28.0

What OS is your Audiobookshelf server hosted from?

Looks like your audio files are either corrupt/need the metadata replaced, or you are running into xHE-AAC issues which will not be supported by Audiobookshelf out of the box. More information in
