Can't Sync Certain Library Types

[JNR8]

I am having trouble Syncing my TV Libraries. But only one of them (I have more than one). The largest one fails with the error below, but the smaller noe works fine.

I get the following response when attempting to sync the largest of the two libraries: Cannot read property 'Video' of undefined at /usr/local/lib/node_modules/plex-sync/lib/plex.js:124:36 at Array.forEach () at /usr/local/lib/node_modules/plex-sync/lib/plex.js:123:23 at at process._tickCallback (internal/process/next_tick.js:188:7)

Possibly the same as issue #75 but that post does not give much information to go on.

Additionally, I cannot Syn c Libraries that do not contain video in them. is this by design? I am attempting to sync the listend to status of Audiobooks. As these are just audio files I thought it might be possible. Can you advise if Plex Sync will sync this type of media' status?
