手机预览微信小程序下，界面报错:
MiniProgramError{"errMsg":"translateMapMarker:fail error markerid"}
Object
说明，我没有用到map 的 marker属性
代码片段：
template 标签对下
map class="map" id="myMap" show-location="true" :polyline="polyline" :longitude="longitude" :latitude="latitude" scale="15" /map
script 标签对下
var _this, mapCtx;
data(){
return{
polyline: [{ points: [] }, { width: 20 }, { color: '#0000AA' }, { borderWidth: 20 }],
latitude: '',
longitude: '',
};
}
onLoad(option) {
_this = this;
mapCtx = uni.createMapContext('myMap',this);
}
问题困扰了一天了，没有找到解决方案，麻烦懂map的大佬们给看一下
