Selenium Chrome 驱动程序 v92：无连接（在 v91 中一切正常）
Selenium Chrome Driver v92: No connection (in v91 everything works fine)
我更新到 Chrome v92（新的 chrome 驱动程序 92.0.4515.43 已下载并且 chrome 浏览器自动更新到 v92）
但现在我们的测试在由 jenkins 启动时不再有效。当我手动启动测试时，一切都在无头模式下工作。
通过 jenkins 发生以下错误：
org.openqa.selenium.SessionNotCreatedException: Could not start a new session. Response code 500. Message: session not created

这是代码，chrome初始化
System.setProperty("webdriver.chrome.driver", FilePath + "\drivers\chromedriver.exe");
HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
chromePrefs.put("profile.default_content_settings.popups", 0);
chromePrefs.put("download.default_directory", FilePath);
ChromeOptions options = new ChromeOptions();
HashMap<String, Object> chromeOptionsMap = new HashMap<String, Object>();
options.setExperimentalOption("prefs", chromePrefs);
options.addArguments("--disable-notifications");
options.addArguments("--disable-popup-blocking");
options.addArguments("--headless");
options.addArguments("--disable-gpu");
options.setCapability(ChromeOptions.CAPABILITY, chromeOptionsMap);
options.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
options.setCapability(ChromeOptions.CAPABILITY, options);
options.setPageLoadStrategy(PageLoadStrategy.NORMAL);
driver = new ChromeDriver(options);
安装 Chrome v91 和 chrome 驱动程序 v91 时一切正常。所以问题与对 v92 的更新有关。
有人有想法吗？
有时会出现此错误：

尝试执行您的代码：
options.addArguments("--no-sandbox");
options.addArguments("--disable-dev-shm-usage");
/dev/shm 分区在某些 VM 环境中太小，导致 Chrome 失败或崩溃（请参阅 http://crbug.com/715363）。使用此标志解决此问题（临时目录将始终用于创建匿名共享内存文件）。

添加这两行代码对我有用：

options.addArguments("--disable-extensions");
