hi this was working in the past and now giving me python errors :

binary_sensor:

• platform: command_line
  name: frigate HTTP Response Status
  command: curl -I http://192.168.1.31:5000/api/

now i get :

Traceback (most recent call last):
File "/usr/src/homeassistant/homeassistant/helpers/entity_platform.py", line 361, in _async_setup_platform
await asyncio.shield(task)
File "/usr/src/homeassistant/homeassistant/components/command_line/binary_sensor.py", line 52, in async_setup_platform
name: str = binary_sensor_config.get(CONF_NAME, DEFAULT_NAME)
