Current Behavior

When I try to sync my calibre database from within LazyLibrarian, I get the following error in my log:
Extra data: line 29645 column 2 (char 639419) [calibre.py:371 (CalSync)]

I'm not sure if this is being caused by LazyLibrarian itself or the calibredb binary that is added by the docker mod.

Expected Behavior

To be able to sync calibre database to LazyLibrarian without error.

Steps To Reproduce

Add universal-calibre docker mod to lazylibrarian docker container and run.

Instigate a calibre sync.

Error.
