Homekit Controller error after upgrade to 0.90.1

After upgrading to 0.90.1 I receive the following error:

homekit_controller: Error on device update!
Traceback (most recent call last):
File “/usr/local/lib/python3.7/site-packages/homeassistant/helpers/entity_platform.py”, line 248, in _async_add_entity

new_values_dict = await self._accessory.get_characteristics(
AttributeError: ‘HKDevice’ object has no attribute ‘get_characteristics’

It was working pre-upgrade. My setup is Hass.io on a Raspberry Pi.

I’ve searched the forums and googled it, but to no avail. Does anyone know what might be causing the error?
