cordova-plugin-background-geolocation: why getValidLocations() method gives duplicate data ?

I am using getValidLocations() method for retrieved stored location and push to server. after pushed i used deleteAllLocations() method for delete stored locations.

But many times getValidLocations() method gives me duplicate data , i think its due to plugin updates location two times at same time.

Your Environment

• Plugin version: 2.3.5

• Platform: iOS

• OS version: 10.2.1

• Device manufacturer and model: iPhone 5s

• Cordova version (cordova -v): 8.0.0

• Cordova platform version (cordova platform ls): 4.5.4

• Plugin configuration options: let config = { desiredAccuracy: 0, stationaryRadius: 50, distanceFilter: 200, notificationTitle: 'XYZ', notificationText: 'ENABLED', foregroundService: true, debug: true, locationProvider: 1, interval: 120000, fastestInterval: 120000, url: 'http://....', httpHeaders: { "Content-Type": "application/json" }, postTemplate: { "UserId": this.UserId, "LocationData": [ { "Lat": this.lat, "Long": this.lng, "Date": this.cuuDate, "BatteryPerc": this.batteryLevel } ] }, method: 'POST', autoSync: true, saveBatteryOnBackground: false, stopOnTerminate: false, startOnBoot: true };

Context

getValidLocations() method gives duplicate entry.

Expected Behavior

i think , its due to plugin updates two or three times at same time

Actual Behavior

My Code is Below… ` startBackgroundLocation() {

      this.UserId = 4

    let config = {

desiredAccuracy: 0, stationaryRadius: 50, distanceFilter: 200, notificationTitle: ‘XYZ’, notificationText: ‘ENABLED’, foregroundService: true, debug: true, locationProvider: 1, interval: 120000, fastestInterval: 120000, url: ‘http://…’, httpHeaders: { “Content-Type”: “application/json” }, postTemplate: { “UserId”: this.UserId, “LocationData”: [ { “Lat”: this.lat, “Long”: this.lng, “Date”: this.cuuDate, “BatteryPerc”: this.batteryLevel } ] }, method: ‘POST’, autoSync: true, saveBatteryOnBackground: false, stopOnTerminate: false, startOnBoot: true }; this.backgroundGeolocation.configure(config).subscribe((location) => {

           console.log('configuration: '+JSON.stringify(location));

           console.log('Lat: '+location.latitude + ' :: '+location.longitude );

           this.lat = location.latitude;
           this.lng = location.longitude;

           this.cuuDate = new Date();
           this.cuuDate = moment(this.cuuDate).format('YYYY-MM-DDTHH:mm:ss');
           console.log('current date and time : '+this.cuuDate);
           const subscription = this.batteryStatus.onChange().subscribe(status => {
               console.log(status.level, status.isPlugged);
               this.batteryLevel = status.level;
           });

           if( this.httpService.isOnline() ) {
               this.arrLocations = [];
               // this.arrLocations = this.dbHandlerProvider.get_location();

                        } else {
                            this.arrLocations.push({
                                Lat: res[i].latitude,
                                Long: res[i].longitude,

                                BatteryPerc: this.batteryLevel

                    setTimeout(()=> {
                        console.log('Back Location Data: '+JSON.stringify(this.arrLocations));
