Users sync

[MoonshineSG]

Trying to sync the view status of 2 users on the same server

DRY_RUN=1 plex-sync token_user1@192.168.1.11/2,r token_user2@192.168.0.111/2,w

and I always get

TypeError: Cannot read property '$' of undefined

• user_1 is the main users and user_2 is managed
• plex-sync@0.6.1
• plex-server@1.13.8.5395

Any ideas what could be wrong ?
