forEachFeatureAtPixel layerFilter not excute in right way

[erDuo10]

onMapPointerMove(e) {
  let hitFeature = this.$refs.map.$map.forEachFeatureAtPixel(
    e.pixel,
    this.handleDemanderFeatureClick,
    { layerFilter: function(layer) {
        const id = layer.get("id");
        return id != undefined && id.startsWith('wells-status');
      }
    }
  )

  console.error('onMapPointerMove hitFeature:', hitFeature);
},
 handleDemanderFeatureClick(feature, layer ){
   console.error('handleDemanderFeatureClick feature:', feature);
   console.error('handleDemanderFeatureClick layer:', layer);

   return feature;
 },

as the code show, layerFilter do not implement filter use, the filter code could not trigger the callbak method handleDemanderFeatureClick.

after delete the filter, the onMapPointerMove trigger many a time

Hello @erDuo10 ,

You should check layer id is correct, and is it "managed"(not added as overlay) layer, is it vector layer and etc.
There is extended documentation https://openlayers.org/en/v6.15.1/apidoc/module-ol_Map-Map.html#forEachFeatureAtPixel, when call though this.$refs.map.$map.forEachFeatureAtPixel.
There is also a demo https://jsfiddle.net/ghettovoice/Ln9qr135/460/
