I'm trying to use multiple options on my selenium project with Chrome as driver, but when i try to add headless + extension i got an error
System.InvalidOperationException occurred HResult=0x80131509

my code is:
var option = new ChromeOptions();
option.AddArguments("--headless --disable-gpu");
option.AddExtensions(#"EXTENSION PATH");
var driver = new ChromeDriver(option);
var action = new Actions(driver);
driver.Navigate().GoToUrl(URL);
if i use only the extension or argument it works.
How can i use both? Or i cant?
Thank in advance.
A few points:
Though the arguments --headless and --disable-gpu are interrelated but are used for separate tasks. Hence we need to specify them separately.
Use optimal code block and comment/remove the debug/unused code. As driver.Navigate().GoToUrl(URL); doesn't need WebDriver instance to be casted so we need to comment/remove var action = new Actions(driver);
Your final code block will look like:
var option = new ChromeOptions();
option.AddArguments("--headless");
option.AddArguments("--disable-gpu");
option.AddExtensions(#"EXTENSION PATH");
var driver = new ChromeDriver(option);
driver.Navigate().GoToUrl(URL);

I'm currently facing an issue trying to run a selenium web automation with firefox(headless) on azure devops, I have the same browser version installed on the windows agent but still I get errors.
It works fine for Chrome on Azure and also locally it works fine for firefox so not really sure what is causing this issue.
These are the logs:

Based on this looks like the browser it's opening but not able to navigate the website not really sure.
Hopefully someone has some idea of what could be the issue, thanks!
This error message...
OpenQA.Selenium.WebDriverTimeoutException : Timed out after 30 seconds
----> OpenQA.Selenium.NoSuchElementException : Unable to locate element: //h2[contains(text(),'Sign in with your email address')]
...implies that NoSuchElementException while trying to locate the element with the locator strategy.
Generally <h2> tags are header elements. Ideally, to locate any visible element you need to induce WebDriverWait for the ElementIsVisible() and you can use the following Locator Strategy:
Using XPath:
new WebDriverWait(driver, TimeSpan.FromSeconds(20)).Until(ExpectedConditions.ElementIsVisible(By.XPath("//h2[contains(., 'Sign in with your email address')]")));
Below is the selenium script to open chrome browser in C# on Windows 10 Visual Studio Code. I'm using Chrome 74 (64 bit) and corresponding ChromeDriver 74.0.3729.6. One thing to note is Chrome is not installed in default directory. This is due to our Office security purpose. It has installed in a different location. When I run the script It gives me error -Failed to create a Chrome process. Could some one please help me to understand why chrome browser isn't opening?

I think your just missing the executable name, like so for example
var chromeOptions = new ChromeOptions()
{
BinaryLocation = "D:\\Chrome\\chrome.exe"
};
var driver = new ChromeDriver(chromeOptions);
here is my setup:
I've tried various driver/webdriver/grid versions, added capabilities just in case one mandatory was missing but had the same result.
Error also present if I delete the driver.exe file so this shouldn't be considered.
Start grid with bat file
start cmd /k java -jar grid3.14.jar -role hub -newSessionWaitTimeout 10
start cmd /k java -jar grid3.14.jar -role node -hub http://192.168.1.229:4444/grid/register
Execute C# code bellow
var options = new ChromeOptions();
var uri = new Uri("http://192.168.1.229:4444/wd/hub");
var driver = new RemoteWebDriver(uri, options);
Test fails with error:

I am trying to get selenium grid working for the first time.
In the setup i have the following
Driver = new ChromeDriver(AppDomain.CurrentDomain.BaseDirectory + "../../../Drivers");
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities = DesiredCapabilities.Chrome();
capabilities.SetCapability(CapabilityType.BrowserName, "chrome");
capabilities.SetCapability(CapabilityType.Platform, new Platform(PlatformType.Windows));
Driver = new RemoteWebDriver(new Uri("http://localhost:4444/wd/hub"), capabilities);
This is in c# using XUNIT and executed using resharper.
I get the error in visual studio

This is my first attempt to work with selenium grid, any guides or tips will be extremely appreciated.
I followed this guide - https://seleniumautomation84.wordpress.com/2014/08/06/selenium-grid-fundamentals-implemented-in-c/
Thanks in advance
I found this
https://github.com/SeleniumHQ/selenium/issues/4461
After updating selenium to 3.7.0 I was no longer getting this error.
Apparently, there is an issue with Selenium Grid 2 and Selenium 3.4/5 so updating your NuGet package the latest version will fix this issue.
I am trying to write a test using C# under Mac. I was able to run tests on Chrome, but now I am going to the next step, by trying to initialize Internet Explorer located on a Windows VM I am using.
So in the VM I started first the selenium standalone server with the following command:
java -jar selenium-server-standalone-3.3.0.jar -role hub
Then, I connected a hub to it from the same VM:
java -jar -Dwebdriver.ie.driver=IEDriverSetup.exe selenium-server-standalone-3.3.0.jar -role node -hub http://192.168.1.4:4444/grid/register
I see from the logs that the node registers to the hub and listens for events and also am able to see in the hub's log that the node has registered.
192.168.1.4 is the IP if the Windows VM, where host the hub and note are located
Until now everything seems to be fine, now I write the following C# code to connect to hub:
`
private IWebDriver driver;
try {
DesiredCapabilities ip = DesiredCapabilities.InternetExplorer();
Uri URL = new Uri("http://192.168.1.4:4444");
driver = new RemoteWebDriver(URL, ip);
catch (Exception e) {
string stack = e.StackTrace;
}
`
When executing the code I get the following error:
`
{System.InvalidCastException: Specified cast is not valid.

`
I tried with Webdriver and Internet explorer versions 3.1.0, 3.3.0 and 3.4.0
I get the same error.
Does anyone have any idea what am I doing wrong? Doesn't seem to be a cast I am doing. the issue occurs at this line:
driver = new RemoteWebDriver(URL, ip);
I even tried
driver = (IWebDriver)new RemoteWebDriver(URL, ip);, but still the same.
It's the same if I try initializing Firefox. I am pretty sure it's not the IE capabilities. I get the same thing if i use
DesiredCapabilities.Firefox()
