BackgroundGeolocation.ready({
			// Geolocation Config
			desiredAccuracy: BackgroundGeolocation.DESIRED_ACCURACY_HIGH,
			logLevel: BackgroundGeolocation.LOG_LEVEL_VERBOSE,
			stopOnTerminate: false, // Allow the background-service to continue tracking when user closes the app.

			httpRootProperty: '.', // specify data as root of json
			locationTemplate: '{"latitude":<%= latitude %>,"longitude":<%= longitude %>}',

				title: 'Driver Mobile',

		}).then(() => {
			console.log('- BackgroundGeolocation is configured and ready');
		});

Expected Behavior

When setting the locationTemplate config, it should create the JSON request with the specified names and inserted variables.

Actual Behavior

The resulting JSON request to the API has the default named JSON property names.

Context

I am trying to send a JSON body to my API that looks like

{longitude: -86.15916036467566, latitude: 39.7706582761631, fromNotification: false, osVersion: "2.10.0"}

But instead, with the given config, it ends up looking like

{lng: -86.15916036467566, lat: 39.7706582761631, fromNotification: false, osVersion: "2.10.0"}
