Today I was able to get another similar error. This one is very rare though, I've seen it only once so far.

Just got the same error during the execution on ADO Windows agent and Chrome 97: https://dev.azure.com/aquality-automation/aquality-automation/_build/results?buildId=1757&view=logs&s=859b8d9a-8fd6-5a5c-6f5e-f84f1990894e&j=16f81312-b5db-5d03-2d86-5b7533053f9f

I am getting this error as well @mialeska or @Dreamescaper, were you able to resolve this?
@rhamblin I ended up ditching WebDriver's Network classes, and used ChromeDevTools directly:
_devTools = ((IDevTools)_driver).GetDevToolsSession().GetVersionSpecificDomains<DevToolsSessionDomains>();
await _devTools.Network.Enable(new EnableCommandSettings());
_devTools.Network.RequestWillBeSent += RequestWillBeSent;
_devTools.Network.ResponseReceived += ResponseReceived;
_devTools.Network.LoadingFinished += LoadingFinished;
Just to check if this is still valid, is this happening also with the most recent version (4.4.0)?
yes, it is happening for me as well on both 4.4.0 and 4.5.0
still happening - anyone has a workaround for it?
I can also confirm that it's still happening with the latest version
The current DevTools implementation in .NET is not ideal, and we are looking for people who are interested in making it better.
I have changed Selenium to Playwright and everything works well.
Have same issues, random exceptions going through:
using IWebDriver driver = new ChromeDriver(chromeOptions);
_manager = new NetworkManager(driver);
_manager.NetworkResponseReceived += ResponseHandler;
_manager.StartMonitoring();
driver.Navigate().GoToUrl(url);
My usings:
<PackageReference Include="Selenium.Chrome.WebDriver" Version="85.0.0" />
<PackageReference Include="Selenium.WebDriver" Version="4.8.1" />
<PackageReference Include="Selenium.WebDriver.ChromeDriver" Version="111.0.5563.6400" />
<PackageReference Include="Selenium.WebDriver.Extensions" Version="4.1.0" />
Hi I'm using selenium (c#) with proxy:
Proxy proxy = new Proxy();
string proxyAddress = "http://ip:port";
proxy.HttpProxy = proxyAddress;
proxy.SslProxy = proxyAddress;
ChromeOptions options = new ChromeOptions();
options.Proxy = proxy;
ChromeDriver driver = new ChromeDriver(options);
NetworkAuthenticationHandler handler = new NetworkAuthenticationHandler()
{
UriMatcher = _ => true,
Credentials = new PasswordCredentials("admin", "password")
};
INetwork networkInterceptor = driver.Manage().Network;
networkInterceptor.AddAuthenticationHandler(handler);
networkInterceptor.StartMonitoring().Wait();
driver.Navigate().GoToUrl("https://exampleurl.com");
networkInterceptor.StopMonitoring().Wait();
driver.Quit();
I'll add that I'm running this code in a loop with intervals of 30 seconds and every time the following exception is thrown after different amount of iterations:
DevTools listening on ws://127.0.0.1:50303/devtools/browser/367n89mk-ii5e-41a4-5867-8p1f56b8524l

This error is a showstopper (application crash). Does anybody succeeded to find a solution to this error ? Or alternatively, Is there any other way to use proxy with selenium (c#) without the Network classes ? Thanks
Fixed by https://github.com/SeleniumHQ/selenium/pull/12486, try the latest v4.12.2

What happened?
We use Network monitoring to log requests and responses for failed tests.
Unfortunately, sometimes we receive the following errors:
It happens it random places, and we cannot reproduce that consistently. Even worse that it makes the whole test run crash.
How can we reproduce the issue?
Unfortunately, I don't know how to reproduce this issue consistently. Sometimes it happens, sometimes it doesn't. I'll update this issue if I am able to find a repro case
