根据您描述的问题，在鸿蒙平台上使用uni-app更新地图markers不生效，主要原因如下：

缺少唯一标识id：鸿蒙地图要求每个marker必须有唯一id属性用于识别更新。您的代码中未设置id字段，导致系统无法区分新旧标记点。
鸿蒙平台特殊实现：与App平台不同，鸿蒙地图的updateMarkers需要完整替换标记点集合，而非增量更新。建议先调用mapContext.clearMarkers()清除现有标记，再通过mapContext.addMarkers()添加新标记。
数据格式验证：请确认经纬度值是否为有效数字（Number类型），且iconPath的base64格式需符合鸿蒙规范。部分特殊字符可能导致解析失败。
API调用时机：确保在地图组件loaded事件触发后再调用更新方法，避免因地图未初始化完成导致操作失效。

解决方案：

// #ifdef APP-HARMONY  
const mapContext = uni.createMapContext('map', this);  
mapContext.clearMarkers(); // 先清除  
setTimeout(() => { // 确保清除完成  
  mapContext.addMarkers({  
    markers: this.ismarkers.map((item, i) => ({  
      ...item,  
      id: i + 1, // 必须添加唯一id  
      width: 30,  
      height: 30  
    }))  
  });  
}, 100);  
// #endif

建议参考uni-app鸿蒙地图文档确认最新API规范。当前uni-app x 4.86版本对鸿蒙地图支持更完善，建议升级HBuilderX至最新alpha版。
