arcgis api for js 4.11最新版featurelayer中数据源使用source时,heatMap怎么出不来,也不报错

在网上看到一个用3.23版本featurelayer,数据源用的source可以使用热力图,为什么4.11不可以啊?求大神指教,万分感谢

//创建FeatureLayer图层
const featureLayer = new FeatureLayer({
source: features,
fields: [{
name: "num",
type: "integer",
alias: "num"
}],
objectIdField: "ObjectID",
geometryType: "point",
renderer: renderer
});
这个sorce:features是我自己的json数据,这样的featureLayer用这个heatmap不起作用。。。
