[WebDriverException，同时尝试截取屏幕截图

Question

因此，我试图从firefox浏览器中截取屏幕截图，但出现以下异常：

org.openqa.selenium.WebDriverException: [Exception... "Data conversion failed because significant data would be lost"  nsresult: "0x80460003 (NS_ERROR_LOSS_OF_SIGNIFICANT_DATA)"  location: "JS frame :: resource://gre/modules/AsyncShutdown.jsm :: observe :: line 551"  data: no]

    ....

抛出它的Java代码行：

File srcFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);

该代码在多台计算机上都能正常工作，但是尝试在新计算机上安装后，出现此错误

有人知道是什么原因吗？我从容器中运行应用程序

检查您尝试截取其元素的可见性。我试图为一张桌子拍照，里面有看不见的元素，这压碎了程序
