Homebridge is throwing an error for Country Code 
**Describe The Bug:**
Homebridge cannot send commands to LG devices and displays "This plugin threw an error from the characteristic 'Target Heater-Cooler State': Unhandled error thrown inside write handler for characteristic: Cannot read properties of undefined (reading 'countryCode'). See https://homebridge.io/w/JtMGR for more info."

**To Reproduce:**
It happens just by being on and running. I receive the error any time I try to send a command to turn on my AC/heaters.

**Expected behavior:**
The AC/heater should turn on with no error.
