Failed to cancel remote start

[garyd9]

2023 Chevy Bolt EUV with all the onstar packages (still in my free trial period for "premium"), the plugin successfully remote starts the car using the climate switch. Setting the climate switch to "off" seemingly should cancel the remote start (turn off the car) but doesn't.

The following log entry shows up in homebridge when trying to cancel (VIN and tokens replaced with x's):
