[🐛 Bug]: Cannot open Chrome session with incognito mode along with Bidi CDP

[datxhoang]

What happened?

I would like to open Google Chrome session as incognito mode with Bidi CDP but the Chrome window created then disappear right after then throw the error. I am using:

• Java 17
• Selenium 4.22.0

Just write the simple unit test then you can see the issue.

How can we reproduce the issue?

@Test
    public void test() throws Exception {
        ChromeOptions chromeOptions = new ChromeOptions();
        chromeOptions.addArguments("incognito");
        chromeOptions.setCapability("webSocketUrl", true);

        WebDriver webDriver = new CChromeDriver(chromeOptions, 0);
        webDriver.get("https://google.com");
    }

Relevant log output

Hello,

update it as follows and the problem will be solved.

@Test public void test(){ ChromeOptions chromeOptions = new ChromeOptions(); chromeOptions.addArguments("incognito"); WebDriver driver = new ChromeDriver(chromeOptions); DevTools devTools = ((HasDevTools) driver).getDevTools(); devTools.createSession(); devTools.send(Network.enable(Optional.empty(), Optional.empty(), Optional.empty())); driver.get("https://google.com"); }

Hello @dogukankoylu do

My run was says that org.openqa.selenium.devtools.DevToolsException: You are using a no-op implementation of the CDP. The most likely reason for this is that Selenium was unable to find an implementation of the CDP protocol that matches your browser. Please be sure to include an implementation on the classpath, possibly by adding a new (maven) dependency oforg.seleniumhq.selenium:selenium-devtools-vNN:4.22.0whereNNmatches the major version of the browser you're using. Build info: version: '4.22.0', revision: 'c5f3146703' System info: os.name: 'Mac OS X', os.arch: 'aarch64', os.version: '14.5', java.version: '17.0.10' Driver info: DevTools Connection

So it means I have to add the devtool lib into the classpath with the corresponding version. And if yes so let us say, I have a lot of laptops so I have to do it manually for all of them?
