鸿蒙os获取相机拍摄图片

Question

您好，我在复现您的代码<【鸿蒙应用ArkTS开发系列】- 选择图片、文件和拍照功能实现>时候，出现一个问题，
调用相机拍照后无法显示拍照的图片，并且返回url是空值。

错误项为
11-27 21:53:22.301 30935-11718/com.example.myapplication E 03900/Ace: [jsi_declarative_engine.cpp(CallAppFunc)-(0)] property "default" is not a object

拍照类中startAbility call back的值result是空值
11-27 21:53:26.407 30935-11718/com.example.myapplication I 0FEFE/JsApp: MediaHelper startAbility call back , {"resultCode":0,"want":{"deviceId":"","bundleName":"","abilityName":"","moduleName":"","uri":"","type":"","flags":0,"action":"inline-data","parameters":{"data":{},"moduleName":""},"entities":[]}}
11-27 21:53:26.407 30935-11718/com.example.myapplication I 0FEFE/JsApp: 进入拍照类003，uri：undefined
下方是图片

出问题的代码

  public async takePhoto(context: common.UIAbilityContext): Promise<MediaBean> {

console.info("进入拍照类")
    let want = {
      'uri': '',
      'action': wantConstant.Action.ACTION_IMAGE_CAPTURE,
      'parameters': {},
    };
    console.info("进入拍照类001")
    return context.startAbilityForResult(want)
      .then((result) => {
        console.info("进入拍照类002")
         console.info(this.TAG, `startAbility call back , ${JSON.stringify(result)}`);
        if (result.resultCode === 0 && result.want &&(result.want.uri==null||result.want.uri=="")==false) {
          //拍照成功
          //  console.info(this.TAG, 'takePhoto successfully, takePhotoResult uri: ' + result.want.uri);
          return result.want.uri;
        }
      }).catch((error) => {
        console.info("进入拍照类error")
        console.info(this.TAG, `startAbility error , ${JSON.stringify(error)}`);
        return error;
      }).then(async (uri: string) => {
        console.info("进入拍照类003，uri："+uri)
        const mediaBean = await this.buildMediaBean(uri);
        return mediaBean;
      });
  }
