Typescript error GeoJSONFeature: Property coordinates does not exist on type Geometry

[guilledll]

Hi all, i'm currently working with MapTiler which uses MapLibre under the hood, my setup is Vue 3 + TS.

I'm facing a missing type declaration issue inside map listeners and in GeoJSONFeature usage in general, when calling event.features[0].geometry.coordinates inside map event listener I got the error:

Property 'coordinates' does not exist on type 'Geometry'.

But in reality this works fine, coordinates end up being [coord1, coods2] as expected, the only issue is the Type definition.

In the source code the implementation looks good, but for some reason .coordinates is not inferred from the return of the function?

maplibre-gl-js version: 5.6

browser: Chrome

Steps to Trigger Behavior

1. Initialize a map
2. Create an event listener over a feature
3. Access event.features[0].geometry.coordinates to see the error

Expected Behavior

GeoJSONFeature -> geometry.coordinates value should appear in TS definitions?

Actual Behavior

TS is rising an error: Property coordinates does not exist on type Geometry. Property coordinates does not exist on type GeometryCollection<Geometry>

Workaround

Is it possible to suppress this error by commenting above the line:

// @ts-expect-error - Property 'coordinates' does not exist on type 'Geometry'.
const coords = e.features[0].geometry.coordinates

Some geojson features have coordinate and other have coordinates. You need to cast or check the type.

I was able to properly access coordinates by previously checking with:

if (event?.features?.[0]?.geometry?.type === "Point") {
  // Type safe `feature.coordinates`
  const coords = event.features[0].geometry.coordinates
}

Thank you @HarelM !
