The problem

Pull request #40520 has added an un-intended side effect issue with setting presets.

If the Ecobee Hold Action preference is anything other than "Until the next scheduled activity" it throws an error as it appears to not pass the holdHours variable that it is requesting. This includes setting a preset via the Lovelace UI and automations.
