Hi all, i run Hassio core-2021.3.4 (latest version) on a Rasp 3B+ and for some reason,in the last days i am unable to make a backup.
When i try to take a snapshot, after some minutes HA give me a message error and in Supervisor log i have this error codes:
21-03-30 21:36:03 ERROR (MainThread) [asyncio] Task exception was never retrieved
future: <Task finished name='Task-798' coro=<HomeAssistantWebSocket.async_supervisor_update_event() done, defined at /usr/src/supervisor/supervisor/homeassistant/websocket.py:133> exception=TypeError('Received message 257:None is not str')>
