[🐛 Bug]: DotNet WebDriver msedge(Ver:103.0.1264.77）Use EdgeOptions DebuggerAddress is 127.0.0.1:50521 Error

[flysky2005]

What happened?

OpenQA.Selenium.WebDriverArgumentException: invalid argument: entry 0 of 'firstMatch' is invalid from invalid argument: cannot parse capability: ms:edgeOptions from invalid argument: unrecognized msedge option: excludeSwitches 在 OpenQA.Selenium.WebDriver.UnpackAndThrowOnError(Response errorResponse) 在 OpenQA.Selenium.WebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters) 在 OpenQA.Selenium.WebDriver.StartSession(ICapabilities desiredCapabilities) 在 OpenQA.Selenium.WebDriver..ctor(ICommandExecutor executor, ICapabilities capabilities) 在 OpenQA.Selenium.Chromium.ChromiumDriver..ctor(ChromiumDriverService service, ChromiumOptions options, TimeSpan commandTimeout) 在 OpenQA.Selenium.Edge.EdgeDriver..ctor(EdgeDriverService service, EdgeOptions options, TimeSpan commandTimeout) 在 XRBrowser.MainForm.CreateEdgeDriver(Boolean& isRunning)）

How can we reproduce the issue?

var options = new EdgeOptions();
var debugHost = "127.0.0.1";
var debugPort = 50521;
options.DebuggerAddress = $"{debugHost}:{debugPort}";
driver = new EdgeDriver(driverService, options, TimeSpan.FromSeconds(40));

I was able to see the issue. We are going to work on it. As a workaround for now, please comment out the line below and it should work.

EdgeOptions options = new EdgeOptions();
options.AddArguments("start-maximized");
options.AddExcludedArgument("enable-automation");

var debugHost = "127.0.0.1";
var debugPort = 45411;
options.AddArgument($"remote-debugging-host={debugHost}");
options.AddArgument($"remote-debugging-port={debugPort}");
//options.DebuggerAddress = $"{debugHost}:{debugPort}"; <== Comment out this line

EdgeDriver driver = new EdgeDriver(options);
driver.Navigate().GoToUrl("https://www.bing.com/");
driver.Quit();

I was able to reproduce the issue and triage it. There is a bug in how Selenium C# is sending "debuggerAddress" to the browser. It should be part of the "args" but sending it as a capability.

{[]: newSession {"capabilities":{"firstMatch":[{"browserName":"chrome","goog:chromeOptions":{"args":["start-maximized","--remote-debugging-host=127.0.0.1","--remote-debugging-port=45411"],"debuggerAddress":"127.0.0.1:45411","excludeSwitches":["enable-automation"]}}]}}}

I have some changes made on my local to fix it but I am still iterating over the best way to fix this. Meanwhile, please use the code snippet below as a workaround:

 EdgeOptions options = new EdgeOptions();

            options.AddArguments("start-maximized");
            options.AddExcludedArgument("enable-automation");

            var debugHost = "127.0.0.1";
            var debugPort = 45411;
            options.AddArgument($"remote-debugging-host={debugHost}");
            options.AddArgument($"remote-debugging-port={debugPort}");
            options.AddArgument($"debuggerAddress={debugHost}:{debugPort}");
            //  options.DebuggerAddress = $"{debugHost}:{debugPort}";

            EdgeDriver driver = new EdgeDriver(options);

            driver.Navigate().GoToUrl("https://www.bing.com/");
            driver.Quit();

According to the Chromedriver docs it is its own capability, and even the driver code itself appears to support it — https://github.com/bayandin/chromedriver/blob/main/capabilities.cc#L598-L599

If it is not working, then I think this is a chromedriver bug, and not a problem with Selenium code.

[pujagani]

+1 with Titus's comment. Selenium seems to have done the right thing. https://chromedriver.chromium.org/capabilities#h.p_ID_102 also mentions it needs to be top-level capability. I could see this error as far as Chrome version 85.

Hi, @flysky2005. This issue has been determined to require fixes in ChromeDriver.

You can see if the feature is passing in the Web Platform Tests.

If it is something new, please create an issue with the ChromeDriver team. Feel free to comment the issues that you raise back in this issue. Thank you.
