HarmonyOS鸿蒙Next中执行fs.listFileSync时返回is not callable错误

根据文档例子，在执行fs.listFileSync的时候，返回is not callable错误，请帮忙看看是哪里问题： 头部已引用：import { fileIo as fs, Filter, ListFileOptions} from ‘@kit.CoreFileKit’; SDK 5.0.4(16)

代码如下

let listFileOption: ListFileOptions = {
  recursion: false,
  listNum: 0,
  filter: {
    suffix: [".png", ".jpg", ".jpeg"],
    displayName: ["*abc", "efg*"],
    fileSizeOver: 1024
  }
};
try{
  console.info("listFile begin");
  let newContext = getContext(this) as common.UIAbilityContext;
  let filenames = fs.listFileSync(newContext.filesDir + '/', listFileOption); //这里出错，e.message返回is not callable
  console.info("listFile succeed");
  for (let i = 0; i < filenames.length; i++) {
    console.info("filename: %s", filenames[i]);
  }
}
catch (e) {
  console.info(e.message)
}
