Essentials java.lang.reflect.InvocationTargetException

[austinnichols101]

I've tried with both 5.6.0 as well as as the 6.0 bleeding edge library. My test code is shown below along with version info.

Any guidance on what else I can test would be greatly appreciated.

import API2
conn = API2.Connection(host='192.168.111.157', port=20059, username='admin', password='changeme')
api = API2.JSONAPI(conn)

# This method works
api.players.name.send_message('testuser', 'Hello World!')

# All of these methods fail
api.essentials.reload()
uuid = api.essentials.users.get_uuid('testuser')
api.essentials.users.player_get_all('testuser')
