HarmonyOS 鸿蒙Next Web组件的webPageSnapshot网页长截屏API使用报错，报错日志：ErrorCode: undefined, Message: is not callable

Web组件，webPageSnapshot这个API用着报错，这是网页长截图、网页快照、获取网页全量绘制结果的API。希望大佬帮忙解决一下。开发工具版本号是：Build Version: 5.0.3.403, built on June 20, 2024

报错日志：ErrorCode: undefined,  Message: is not callable

完整代码案例如下：

//TODO 网页快照、网页长截图、网页全量绘制（API12）
// 文档：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/js-apis-webview-V5
import { webview } from ‘@kit.ArkWeb’;
import { BusinessError } from ‘@kit.BasicServicesKit’;
import { CXNavView } from ‘…/…/common/CXNav/CXNavView’;
@Entry
@Component
struct webPageSnapshotPage {
  controller: webview.WebviewController = new webview.WebviewController();
  aboutToAppear(): void {
    try {
      // 设置开启网页全量绘制能力。仅在web初始化时设置。
      webview.WebviewController.enableWholeWebPageDrawing();
    } catch (error) {
      console.error(enableWholeWebPageDrawing：ErrorCode: ${(error as BusinessError).code}, Message: ${(error as BusinessError).message});
      // ErrorCode: undefined,  Message: is not callable
    }
  }
  build() {
    Column() {
      CXNavView()
      Button(‘网页长截图API12’)
        .onClick(() => {
          try {
            // snapshot的id。
            // web绘制的尺寸，最多支持16000px * 16000px, 长度单位支持px、vp、%，需保持不同参数传入长度单位一致, 默认单位vp，超过规格时返回最大规格。（示例：width:‘100px’, height:‘200px’。或者 width:‘20%’, height’30%’。只写数字时单位为vp。）
            this.controller.webPageSnapshot({ id: “1234”, size: { width: 100, height: 100 } }, (error, result) => {
              if (error) {
                console.error(webPageSnapshot：ErrorCode: ${(error as BusinessError).code}, Message: ${(error as BusinessError).message});
                return;
              }
              if (result) {
                console.info(return value is:${result});
                //开发者可以根据需要处理返回结果
                // 全量绘制结果image.pixelMap格式
                let imagePixelMap = result.imagePixelMap
              }
            });
          } catch (error) {
            console.error(webPageSnapshot：ErrorCode: ${(error as BusinessError).code}, Message: ${(error as BusinessError).message});
          }
        })
      Web({ src: ‘www.example.com’, controller: this.controller })
    }
  }
