Unable to compile config with esphome 2023.12.8

I'm getting this error when trying to compile your configuration:

I renamed the substitution variables in v2.0.x so they match the ESPHome vars exactly, so you'll need to revise the names.

substitutions:
  name: "airgradient-one"
  friendly_name: "AirGradient One"
  config_version: 1.0.0
  name_add_mac_suffix: "false"  # Must have quotes around value

Also wanted to point out that you have logger: in your config, but this is also set in the packages/airgradient_esp32-c3_board.yaml file with the buad_rate set to 0 to disable it, since both hardware UARTs are being used by sensors, so it won't work for logging.

Thanks a lot! It validates now. And installing with the latest ESPHome version works as expected.
