TypeError: json.layers[layerName].feature is not a function

Hi, I have 2 issues with VectorGrid:

1. Errors are popping up in console: TypeError: json.layers[layerName].feature is not a function when tiles are fetched, so when tiles are not found this error comes up. I am using VectorGrid to fetch tilesets from Mapbox Studio. Despite the error the vector tiles display correctly.

Here is a sample of my code:

var layer = L.vectorGrid.protobuf("https://{s}.tiles.mapbox.com/v4/"+tile+"/{z}/{x}/{y}.vector.pbf?access_token={token}", {
			vectorTileLayerStyles: {},
			subdomains: "abcd",
			token: L.mapbox.accessToken,
			interactive: true,
			getFeatureId: function(f) {
                            return f.id; //properties.osm_id;
                       }
		 })
         .on('click', function(e){
         	if(e.latlng && e.layer.properties){
         		var content = self.parseProperties(e.layer.properties);
         		if(content != ""){
         	         var popup = L.popup()
				 .setLatLng(e.latlng)
				 .setContent(content)
				 .openOn(self.mapnew);
         		}
         	}
         }).addTo(self.mapnew); 

2. When I zoom in, the vector tile markers or circlemarkers do not change size smoothly, but still remain on the map creating a messy display. Below are two screenshots.

Any idea how to fix these issues?

It looks like normal behavior until the new, zoomed in tiles have loaded. If they just stay like that forever, something else is going on. I would check for errors in the console.

They do stay like that forever and this error is displayed in the console: TypeError: json.layers[layerName].feature is not a function Leaflet.VectorGrid.Protobuf.js:140:16

This is where the error occurs on lines: for (var i=0; i<json.layers[layerName].length; i++) { var feat = json.layers[layerName].feature(i); feat.geometry = feat.loadGeometry(); feats.push(feat); }

I think it needs to be changed to

for (var i=0; i<json.layers[layerName].length; i++) { if(json.layers[layerName].feature(i)){ var feat = json.layers[layerName].feature(i); feat.geometry = feat.loadGeometry(); feats.push(feat); } }

I am declaring vector grid like that:

It seems like https://unpkg.com/leaflet.vectorgrid@latest/dist/Leaflet.VectorGrid.bundled.js and all the related files are not updated with the latest changes.
