add_id_path error

[ecknight]

Hi Jes,

Thanks for the great package! I'm looking forward to using it. I'm having trouble running the example ee_grab script It's throwing the following error:

"Error in add_id_path(nodes, root_id = root_id, leaf = leaf) :
!anyDuplicated(nodes$id) is not TRUE"

which some googling suggests something has changed on the Google API side of things (the googledrive package has also had similar issues).

Any thoughts? Thanks!
