Leaflet 我尝试将mapbox/geojson vt与传单一起使用，它不是渲染线字符串几何体

我正在尝试在传单地图上实现geojson-vt（）。我可以渲染多边形，但geojson vt没有渲染LineString，即使我已将lineMetrics设置为true。我尝试直接在地图上渲染LineString，但通过geojson-vt无法工作

    parseGeoJSONArray() {
        this.parseVT({type: "FeatureCollection", features:[
                  {

                      "dataType": "topology"
