Neato: Error on device update!

Just updated to latest HA (docker image on a Synology NAS) and Neato component gives me the following:

2019-01-16 15:11:11 ERROR (MainThread) [homeassistant.components.vacuum] neato: Error on device update!
Traceback (most recent call last):

  File "/usr/src/app/homeassistant/components/vacuum/neato.py", line 85, in update
    robot_alert = ALERTS.get(self._state['alert'])
KeyError: 'alert'

Any ideas why?

Apparently fixed in 0.85.1
