So, I was just trying to get current location by using `navigator.getlocation.getCurrentLocation` method in Lightning Web Components. When I check `if(navigator.getlocation)`, this returns `true`. 

But when use the method, it always gives me an error like 

> "afterRender threw an error in 'c:sampleMapComponent' [Cannot read property 'length' of undefined]". 

Below is my code of JS file.

    /* eslint-disable no-console */
    import { LightningElement, track } from 'lwc';
    
    export default class SampleMapComponent extends LightningElement {
        @track mapMarkers;
    
        get findMe() {
            navigator.geolocation.getCurrentPosition(this.success, this.error);
            return this.mapMarkers;
        }
    
        success(position) {
            if (position) {
                console.log('position -> ' + position);
                this.mapMarkers = [
                    {
                        location: {
                            'Latitude': position.coords.latitude,
                            'Longitude': position.coords.longitude
                        },
                        title: "My Location",
                    },
                ]
            }
    
        }
    
        error() {
            console.log('Failed');
        }
    }


Template:

    <template>
    <h1>Current Location</h1>

    <lightning-map map-markers={findMe}></lightning-map>

</template>

Error:

Please let me know what am I doing wrong..I am calling `findMe()` method from template (from map-markers of lightning-map)
