Nonsensical ERA report : Vivoactive 4

Hi,

Although this might be related to : Sensor.setEnabledSensors exception on Venu, Vivoactive 4 - Connect IQ Bug Reports - Connect IQ - Garmin Forums 

I think it is a separate issue!

Over the past three or four days, I have been seeing several ERA reports along the lines of this one:

Error Name: Symbol Not Found Error
Occurrences: 12
First Occurrence: 2020-11-26
Last Occurrence: 2020-11-26
Devices:
    vívoactive® 4: 5.10
App Versions: 0.0.45
Languages: fre
Backtrace:

The line number is a conditional where I check sub-sport based on Activity enumerators: 

function checkEnabledSensors() {
		var subSport = collectSportInfo()[1];
	    var needsGps = storeData;
	    if(	subSport == ActivityRecording.SUB_SPORT_CARDIO_TRAINING || // @@ CRASH ON THIS LINE @@
			subSport == ActivityRecording.SUB_SPORT_INDOOR_CYCLING || 
			subSport == ActivityRecording.SUB_SPORT_SPIN ||
			subSport == ActivityRecording.SUB_SPORT_TREADMILL) {
			needsGps = false;
		}    
        if(needsGps) {		Position.enableLocationEvents(Position.LOCATION_CONTINUOUS, method(:onPosition));		}
		try {
			//https://forums.garmin.com/developer/connect-iq/i/bug-reports/sensor-setenabledsensors-exception-on-venu-vivoactive-4
			if(Sensor has :enableSensorType) {
				Sensor.enableSensorType(Sensor.SENSOR_HEARTRATE);
				Sensor.enableSensorType(Sensor.SENSOR_BIKECADENCE);
				Sensor.enableSensorType(Sensor.SENSOR_BIKEPOWER);
				Sensor.enableSensorType(Sensor.SENSOR_FOOTPOD);
			} else {
				Sensor.setEnabledSensors([Sensor.SENSOR_HEARTRATE,Sensor.SENSOR_BIKECADENCE,Sensor.SENSOR_BIKEPOWER,Sensor.SENSOR_FOOTPOD]);
			}
		} catch(e) {}
    }

So far, I have only seen it on French devices, and only on Vivoactive 4. However, I share this method across two or three apps, and I have observed a similar bug in each of them. 

As you can see, I have already significantly safety checked my "checkEnabledSensors" method as per the previous bug report. 

I can see no way for this to be failing, and certainly no way for it to be failing on that specific line.
