Unable to Sync additional Yang Models

[RunSi]

Hi I am using Yang Explorer on a Mac running 10.11.6 (El Capitan). I am starting Yang Explorer in a virtual environment and have attempted to sync Yang Models from the Devnet CSR (ios-xe-mgmt.cisco.com). Browser being used is Chrome 52.0.2743.116. I have tried using both Python 2.7.8 and Python 3.5, and still receive an error when attempting to sync Yang Models from the 'Manage Models/Device' pane.

Looking at the Bash shell I have running it seems that there is a parsing failure of the downloaded model. Output below:-

Hi, Looks like downloaded yang files are either corrupted or invalid. Please retry sync and if this happens again see if yang-explorer/server/session/ has one or more yang files, if so, make sure they have .yang extension and you are able to manually open in an text editor and in fact they are valid yang modules. You can also zip and send me those files for debugging.

Please let me know if you see this issue again.
