core: August 531 Error when trying to Lock

The problem

When I try to lock my August Lock, I get the following error. It actually does lock, I can see it in the August app, but that state is never reported back to homeassistant. I've deleted the integration, added it again, reauthenticated the token but it doesn't seem to work.

Environment

• Home Assistant Core release with the issue: 0.108.8
• Last working Home Assistant Core release (if known): 0.108.6
• Operating environment (Home Assistant/Supervised/Docker/venv): Hassio
• Integration causing this issue: August
• Link to integration documentation on our website: https://www.home-assistant.io/integrations/august/

Problem-relevant configuration.yaml

no YAML, Configured via the UI.
