HarmonyOS 在一个新的@Entry页面，使用Image组件首次加载本地uri图片时显示空白

@Entry  
@Component  
struct Index {  
  @State imagePath: string = ''  
  private context = getContext(this) as common.UIAbilityContext;  
  
  build() {  
    Row() {  
      Column() {  
        Image(this.imagePath)

          .height(300)  
          .objectFit(ImageFit.Cover)  
          .backgroundColor(Color.Pink)  
          .margin({ bottom: 20 })  
        Button("选择图片")  
          .onClick(() => {  
            this.selectPhoto()  
          })  
      }.width('100%')

    photoSelectOptions.maxSelectNumber = 1; // 选择媒体文件的最大数目  
    photoViewPicker.select(photoSelectOptions).then((photoSelectResult: picker.PhotoSelectResult) => {  
      const fileUri = photoSelectResult.photoUris[0]  
      this.getFileInfo(fileUri)  
    })  
  }  
  async getFileInfo(filePathString: string) {

    const dateStr = (new Date().getTime()).toString()  
    // 临时文件目录  
    let newPath = this.context.filesDir + `/${dateStr + resFile.name}`;
