Scene.pick returning point inside the globe

CesiumJS
3

Hello @Gabby_Getz
I am using following code to pick point on the globe.

function pickCartesianOnGlobe(mousePos: Cesium.Cartesian2, viewer: Cesium.Viewer): Cesium.Cartesian3 | undefined {

        //pick will return the cartesian coordinates
        let cartesian: Cesium.Cartesian3 | undefined = undefined;
        cartesian = viewer.scene.pickPosition(mousePos);
        if (!cartesian) {
            const ray = viewer.camera.getPickRay(mousePos);
            cartesian = viewer.scene.globe.pick(ray, viewer.scene);           
        }
        return cartesian;
}

I hope this helps.
Thank you.
