无效的文件名 - 下载文件

Question

it('Empty download folder  - Sponsor', function () {
    applicationHelper.emptyFolder(dirPath);
    rimraf(dirPath + '*', function () {
        console.log('done');
    });
});
it('Download draft ct - Sponsor', function () {
    clinicalTrialsPage.downloadCt();
    pagesNavigation.navigateToByName('Applications');
    clinicalTrialsPage.selectDownloadOptionsforPartI();
    expect(topBanner.getMessageInToast()).toContain('Successfully Downloaded');
    browser.sleep(10000);
});
it('Check contents of zip', function () {
  let downloadedZip = glob.sync(dirPath + ctNumber + '*.zip');
    var zipFile = fs.readdirSync(dirPath);
    console.log(zipFile);
    zip = new admZip(dirPath + zipFile[0]);
    zip.getEntries().forEach(function (entry) {
        console.log(entry.entryName);
        zipEntry.push(entry.entryName);
    });
    zip.extractAllTo(dirPath + "zip/", false);
    expect(fs.existsSync(downloadedZip[0])).toBeTruthy();
});

我想检查是否存在下载的文件（确实如此），但是脚本持续失败，而错误的文件名无效。 Console.Log（Zipfile）给出了适当的结果。 我将ChromeDriver用于硒量角器，并正确设置了config.js（功能，prefs等）吗？
