Selenium 在IE 11中，量角器测试在等待预期条件时随机失败。presenceOf（）

我正在为非角度应用程序编写ui测试，并在IE11中运行量角器，但它随机失败

await browser.wait(protractor.ExpectedConditions.presenceOf(element(by.name('TOBACO_SCANNED_SERIAL'))),
        5000,
        "serial number input must be present");

这不是等待后事件失败，它只是在这个代码上立即失败。 我正在使用InternetExplorerDriver 32位版本3.4.0和量角器5.4.2

这是错误的完整堆栈跟踪
