Konnected: 'Unknown error occurred' while sensor configuration

  1. go to ‘Integration’
  2. select a board and click ‘Configure’
  3. in the ‘Configure I/O’ menu I do NO changes and press ‘Submit’
    it says - ‘Unknown error occurred’ …
    in the log I got this message:
Logger: aiohttp.server
Source: helpers/data_entry_flow.py:44

Other than this the konnected seems working . however I got a continuous ‘open’ state on a motion sensor which was configured long rime ago but disconnected, no wires connected. I wanted reconfigure it but got this error…
Is it the konnected integration issue on HA ?

Solved. Upgraded to the Latest Core 2021.12.5…
