加载带有卫星基础层的 HERE 地图时，有时会出现此错误：

    Tangram [error]: Error for style group 'non-collision' for tile 13/16/15542/12554/15 Cannot read property 'retain' of undefined: TypeError: Cannot read property 'retain' of undefined

这可以防止瓷砖首先加载。它不会每次都发生。大约十分之三的页面加载。如果平移或切换到 defaultLayers.vector.normal.map 图层，它将开始正确加载切片。

我正在使用 Angular 7.2.15 和 HERE API 3.1。

我正在通过以下方式初始化地图：

const platform = new H.service.Platform({ apikey: apiKey });
const defaultLayers = platform.createDefaultLayers();

const map = new H.Map(
  elementRef.nativeElement, // elementRef:ElementRef from directive constructor
  defaultLayers.raster.satellite.map,
  {
    zoom: 15,
    center: {lat: 0, lng:0}
  }
);

const behavior = new H.mapevents.Behavior(new H.mapevents.MapEvents(map));

const ui = new H.ui.UI(map);
const zoomControl = new H.ui.ZoomControl();
ui.addControl('zoom', zoomControl);

如何在卫星视图中加载地图而不会引发此错误？

该行为的一个可能问题是在加载网页后加载了一些 HERE JS 库。尝试稍后在代码中添加卫星层是否有更好的响应。

// default map base layer 
var map = new H.Map(document.getElementById('mapContainer'),
  defaultLayers.vector.normal.map,{
  center: {lat:52.5160, lng:13.3779},
  zoom: 13
});
// set base layer later 
map.setBaseLayer(defaultLayers.raster.satellite.map);
