[both] cannot read properties error

[quqck2010]

Whilst the artists, albums, genre and charts return with stats, library and tracks give me an error and im not too sure on what is wrong. I loaded my lastfm api and username already and I modified line 5583 for index.js to allow it to load entirely

i get this for tracks and

i get this for library

its my first time doing this so i am not sure on what to do >_>, any help would be appreciated
