In this example, locationType is set to "coordinate-decimal" but the location.uri points to a .geojson resource. This is internally inconsistent and could mislead users; update the example so the locationType matches the referenced/embedded location format (e.g., use geojson/geojson-point for a GeoJSON URI, or change the URI to a coordinate-decimal resource).

Suggested change
locationType: "coordinate-decimal", // or "geojson-point", "geojson", "h3", "geohash", "wkt", "address", etc.
locationType: "geojson", // or "coordinate-decimal", "geojson-point", "h3", "geohash", "wkt", "address", etc.
