Unable to start Raspberry GPIO switch


I have a brand new setup of Hass on Raspberry Pi Buster, with manual installation following the procedure on hass website.
Hass starts up fine until I modify the config file to insert “Switch”.
My config file is as follows:

Configure a default setup of Home Assistant (frontend, api, etc)

  • platform: google_translate


  • platform: rpi_gpio
    invert_logic: true
    22: Top
    23: Bottom
    27: Lights

group: !include groups.yaml
automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml

Here’s the error that is generated when starting Hass:

Does anybody know what to do with this Error?
Still using Python 3.7 .

This guide assumes that you already have an operating system setup and have installed Python 3.8 (including the package python3-dev ) or newer.

Start with updating Python …

Thank you. It works now after upgrading to 3.8
