Instance members of Source doesn't have a type definition.

https://maplibre.org/maplibre-gl-js-docs/api/sources/#geojsonsource-instance-members

Property 'getClusterExpansionZoom' does not exist on type 'Source'.
Property 'getClusterChildren' does not exist on type 'Source'.
Property 'getClusterLeaves' does not exist on type 'Source'.
Property 'setData' does not exist on type 'Source'.

and this causes a TypeScript compiler error.

Please cast source to geojsonsource.

Ok, I could cast to any too xD.
Are you planning to fix this signature? thx

[HarelM]

The source that is returned can be any source , geojson, vector, image etc.
You need to cast it to the relevant type.
Casting to any won't allow you auto complete...

I'm finding this same problem and don't understand how to cast the returned Source as GeoJSONSource.

const features = map.queryRenderedFeatures(e.point, {
      layers: [lyrDef.spec.id]
});
const clusterId = features[0].properties.cluster_id;
const zoom = await map.getSource("sourceid").getClusterExpansionZoom(clusterId);
map.easeTo({
      center: features[0].geometry.coordinates,
      zoom
});

As far as I can tell this mimics the official docs here: https://docs.mapbox.com/mapbox-gl-js/api/sources/#geojsonsource#getclusterexpansionzoom, however, I'm getting a type error on .getClusterExpansionZoom() saying

Property 'getClusterExpansionZoom' does not exist on type 'Source'.ts(2339)

What is the proper way to do this?

For what it's worth, I also get a type error on .coordinates saying it doesn't exist on type Geometry or GeometryCollection, but I don't know if that's related or something else.
