Undefined markerData in asymmetrick-ngx-leaflet-markercluster.mjs:23:1

[vinceclicks]

I have no issues running ngx markercluster, but I keep getting a nagging error in my console.

 ERROR TypeError: Cannot read properties of undefined (reading 'getLatLng')

I'm not quite sure why but for some reason the markerData in the following code is getting read as undefined, even if I default the input of [leafletMarkerCluster]. markerData is undefined on the first pass of ngOnChanges, followed by ngOnInit, and finally it is defined on the second pass of ngOnChanges. This throws 2 of the above errors in the console.

class LeafletMarkerClusterDirective {
    constructor(leafletDirective) {
        // Hexbin data binding
        this.markerData = [];
        // Fired when the marker cluster is created
        this.markerClusterReady = new EventEmitter();
        this.leafletDirective = new LeafletDirectiveWrapper(leafletDirective);
    }
    ngOnInit() {
        this.leafletDirective.init();
        const map = this.leafletDirective.getMap();
        this.markerClusterGroup = L.markerClusterGroup(this.markerClusterOptions);
        // Add the marker cluster group to the map
        this.markerClusterGroup.addTo(map);
        // Set the data now that the markerClusterGroup exists
        this.setData(this.markerData);
        // Fire the ready event
        this.markerClusterReady.emit(this.markerClusterGroup);
    }
    ngOnChanges(changes) {
        // Set the new data
        if (changes['markerData']) {
            this.setData(this.markerData);
        }
    }

Could this be fixed by adding a check for undefined in the spots where this is called? For now I'll just have to let my developers know not to worry about the errors.
