highlightColor defined as a function on CartoLayer doesnt seem to work

[plgagnon2]

This doesnt seem to work. But CartoLayer inherit from MVTLayer which inherit from Layer in the end (I think)
https://deck.gl/docs/api-reference/core/layer#highlightcolor

return new CartoLayer({
  ...cartoLayerProps,
  id: id,
  pickable: true,
  autoHighlight: true,
  highlightColor: (info) => {
    console.log('test')
  },
});

Indeed, CartoLayer inherits from MVTLayer.

Did you try to specify uniqueIdProperty? Needed for highlighting a feature split across two or more tiles if no feature id is provided. More info here.

You have to options:

1. Set it as a CartoLayer prop:

new CartoLayer({
  ...
  uniqueIdProperty: 'your_unique_id_prop',
  autoHighlight: true,
  highlightColor: [0, 0, 255],
});

2. Set it in your useCartoLayerProps hook like:

const uniqueIdProperty = 'your_unique_id_prop';
const cartoLayerProps = useCartoLayerProps({ source, uniqueIdProperty });
