javascript - 如何修复传单 map 中无效的 LatLng 对象 : (NaN, NaN)？

Question

我试图使用 geoJson 文件中的数据绘制多边形，但收到此错误:

Error: Invalid LatLng object: (NaN, NaN)

这是我的代码:

const latLngs = L.GeoJSON.coordsToLatLngs(data,2);
var polygon = L.polygon(latLngs, {color: 'red'}).addTo(map);
map.fitBounds(polygon.getBounds());

数据:
