This is caused by latest release of VP Server having some changes to its bundled library. Since the server upgrade can only upgrade the server application itself but not its runtime and bundled script files, this causing the script files from older version unable to work with the new server. To solve this problem user can simply replace the script file with those from newer version (download below).
