[🐛 Bug]: Selenium 4 WebSocket exception during performing basic authorization C#

[lopukhDA]

What happened?

Hello, currently we are under investigation of the possibility to use Selenium 4 on our project and we are faced with the next issue: During performing the basic authorization, authorization is passing successfully but at the same time we have the next exception

There is already one outstanding 'SendAsync' call for this WebSocket instance. ReceiveAsync and SendAsync can be called simultaneously, but at most one outstanding operation for each of them is allowed at the same time.

Could you please take a look at this issue?

How can we reproduce the issue?

static void Main(string[] args)
        {
            var options = new ChromeOptions();

            var driver = new ChromeDriver(ChromeDriverService.CreateDefaultService(), options, TimeSpan.FromMinutes(2));


            NetworkAuthenticationHandler handler = new NetworkAuthenticationHandler()
            {
                UriMatcher = d => d.Host.Contains("jigsaw.w3.org"),
                Credentials = new PasswordCredentials("guest", "guest")
            };

            var networkInterceptor = driver.Manage().Network;
            networkInterceptor.AddAuthenticationHandler(handler);
            networkInterceptor.StartMonitoring();

            driver.Navigate().GoToUrl("https://jigsaw.w3.org/HTTP/Basic/");

            networkInterceptor.StopMonitoring();
            driver.Quit();
        }

Info for maintainers

Triage this issue by using labels.

If information is missing, add a helpful comment and then I-issue-template label.

If the issue is a question, add the I-question label.

If the issue is valid but there is no time to troubleshoot it, consider adding the help wanted label.

If the issue requires changes or fixes from an external project (e.g., ChromeDriver, GeckoDriver, W3C), add the applicable G-* label, and it will provide the correct link and auto-close the issue.

After troubleshooting the issue, please add the R-awaiting answer label.

Thank you!

@lopukhDA What happens if you use await networkInterceptor.StartMonitoring(); instead of using it without the await as you've done here?

[lopukhDA]

@jimevans Thanks for your suggestion, but it doesn't work. I have the same error.

[jimevans]

@lopukhDA I absolutely cannot reproduce your issue in my environment, even copying and pasting your code into a new project. The only differences are that I'm using 4.1.0 of the .NET bindings and Chrome/chromedriver 96. However, I would encourage you to at least update to 4.0.1, which did contain some refactoring of how websocket communications are handled.

[lopukhDA]

@jimevans I tried updating selenium to version 4.1 and chrome to 96 but it didn't work for me

[jimevans]

Can you try the same experiment using .NET 5 as the framework version to see if it’s an issue inside .NET? That’s not a solution, or even a workaround, I’m just trying to gather appropriate data.

[lopukhDA]

@jimevans Yes, you are correct, this code does work with .NET Core 5, but does not work with .NET Framework 4.7.2.

[diemol]

@lopukhDA just wondering, is this still valid on 4.4.0?

[sbakharev]

Facing similar problems with Selenium.WebDriver 4.5.1 in a .NET Framework 4.7.2 test project. Though I don't use authentication but use network interception, there is a chance that the problem has a wider scope. According to experience of me and my other colleagues (including those who experiment specifically with authentication) there are general problems with CDP WebSocket handling. Everyone who has incorporated WebDriver's Network into .NET Framework tests are facing freezes, slowdowns and intermittent failures up to things like Error while creating session with the driver service. Stopping driver service: Driver server process died prematurely. (our definite winner).

Still broken? :(

[titusfortner]

Supporting .NET Framework with websocket features is unfortunately a low priority for us at this point. The overall BiDi implementation for this language needs some updates, and that might fix things for 4.7, or it might might include a complete rewrite of the .NET bindings to make all the libraries Async. We'll update when we have an idea of which direction we're going with it.

[soroushsarabi]

this way maybe work, it's work for me.

driver.Navigate().GoToUrl("https://....com/app/my-clients/created");

driver.FindElement(By.TagName("Button")).Click();

Task.Run(async () => {

NetworkManager manager = new NetworkManager(driver);

manager.NetworkRequestSent += Network_NetworkRequestSent;

await manager.StartMonitoring();

});

[EstherSaberski]

Hi @titusfortner is there any update about this issue?

[titusfortner]

No updates.

TPAC is in a few weeks and our primary lead on BiDi work will return from leave in a few weeks, so I'm expecting us to have a long conversation about where we are going soon.
