Uncaught TypeError: Cannot read properties of undefined (reading 'lat')

[iamtekson]

I have tried to implement the onClick event using this plugin as below,

const vectorGrid = L.vectorGrid
  .slicer(street, {
    rendererFactory: L.svg.tile,
    maxNativeZoom: 19,
    maxZoom: 20,
    interactive: true,
    getFeatureId: function (f) {
      return f.properties.name;
    },
  })
  .on("click", function (e) {
    console.log(e);
  })
  .addTo(map);

When I clicked the layer, it shows the following error,

Uncaught TypeError: Cannot read properties of undefined (reading 'lat')
    at Object.project (Projection.SphericalMercator.js:24)
    at Object.latLngToPoint (CRS.js:28)
    at i.project (Map.js:993)
    at i.latLngToLayerPoint (Map.js:1015)
    at i.latLngToContainerPoint (Map.js:1072)
    at i._fireDOMEvent (Map.js:1434)
    at i._handleDOMEvent (Map.js:1397)
    at HTMLDivElement.c (DomEvent.js:92)

In this error log, I didn't find the error linked to my vector grid file. Please help me how can I solve this issue?

Note: I have tried this plugin on leaflet versions 1.0.0 and 1.2.0 which are working fine. But with the latest leaflet version, the plugin is out of date.

Add layer style (via option "vectorTileLayerStyles") with

{radius: 15}

.
Radius must be > 10.

This should help.

Mine is working.
I have used:

1. <script src="https://unpkg.com/leaflet@1.9.2/dist/leaflet.js" integrity="sha256-o9N1jGDZrf5tS+Ft4gbIK7mYMipq9lqpVJ91xHSyKhg=" crossorigin=""></script>
2. <script type="text/javascript" src="https://unpkg.com/leaflet.vectorgrid@1.2.0"></script>

function patchVectorGridLayer(obj) {
 // Fix error for point data.
// eg. mouseover does not work without this.
 obj._createLayer_orig = obj._createLayer;
 obj._createLayer = function (feat, pxPerExtent, layerStyle) {
  let layer = this._createLayer_orig(feat, pxPerExtent, layerStyle);
  if (feat.type === 1) {
    layer.getLatLng = null;
  }
  return layer;
};
// do this for chaining
 return obj;
}

just wrap the vectorgrid with patchVectorGridLayer function like :
example :

const vectorGrid =patchVectorGridLayer( L.vectorGrid
  .slicer(street, {
    rendererFactory: L.svg.tile,
    maxNativeZoom: 19,
    maxZoom: 20,
    interactive: true,
    getFeatureId: function (f) {
      return f.properties.name;
    },
  }))
  .on("click", function (e) {
    console.log(e);
  })
  .addTo(map);
