Question

我们有一个自动化的Selenium解决方案，用于管理面板上的一些常规工作。它一直工作到昨天突然它破了。导航很好：

driver.Navigate().GoToUrl(url); // this works just fine

然而，这一行打破了：

var inputs = driver.FindElements(By.CssSelector("input"));

异常消息是：

我不知道这个问题的原因是什么。由于Chrome版本63强制使用HSTS，我认为由于Chrome 63的巨大变化，chromedriver.exe可能存在问题。请帮忙。

Answer 1

套装的评论似乎是正确的（谢谢）。我安装了最新的WebDriver nuget软件包，但没有安装最新的chromedriver.exe。版本2.34修复了它。

将chrome升级到63版后，Selenium ChromeDriver异常
