For this same error there are many questions in Stackoverflow. But none of them solved my problem. So I have to post this again.
My Code:
ChromeOptions options = new ChromeOptions();
options.AddArguments("--disable-gpu");
options.AddArguments("--disable-extensions");
options.AddArgument(#"user-data-dir=C:\Users\myname\AppData\Roaming\Chrome\Profile 6");
options.AddArgument("--profile-directory=Profile 6");
IWebDriver driver = new ChromeDriver(options);
driver.Navigate().GoToUrl("https://google.com");
Initially I was getting an error " Unable to move cache folder, access denied."
then I have added the line options.AddArguments("--disable-gpu"); and the error is gone.
Now my Code is opening the browser with profile : "Profile 6". But after that its throwing the error
Error in the line : IWebDriver driver = new ChromeDriver(options);
"Exception thrown: 'OpenQA.Selenium.WebDriverException' in WebDriver.dll
An unhandled exception of type 'OpenQA.Selenium.WebDriverException' occurred in WebDriver.dll
invalid argument: user data directory is already in use, please specify a unique value for --user-data-dir argument, or don't use --user-data-dir
"
I have already read almost all topics related to this error. Few of them are :
How to open a Chrome Profile through --user-data-dir argument of Selenium
InvalidArgumentException: Message: invalid argument: user data directory is already in use error using --user-data-dir to start Chrome using Selenium
How to initiate a new Chrome session when the default session is already running using ChromeDriver and Chrome through Selenium and Python
I am stuck in this problem for more than a week now. Please help.
EDIT:
To confirm that I am not using the already opened default user profile, I checked Cheome://version to confirm the user data directory path. Its different than the default.
Also I tried to to run the code after closing all the open chrome instances. This Time I have not received the error. The browser opened by the webdriver. But after that nothing happened. The code got time out error after 60 seconds in the line : IWebDriver driver = new ChromeDriver(options);
Possibly you are specifying the wrong directory. Instead of:
C:\Users\myname\AppData\Roaming\Chrome\Profile 6
You need to pass:
C:\Users\myname\AppData\Local\Chrome\Profile 6
So the effective line of code will be:
options.AddArgument(#"user-data-dir=C:\Users\myname\AppData\Local\Chrome\Profile 6");
Update 1
Additionally, you can remove the argument --profile-directory as in:
options.AddArgument("--profile-directory=Profile 6");
Update 2
If I close all the chrome instances and run the code, I am not getting this error means ChromeDriver is able to open the Chrome browsing instance perfectly. But to analyze why nothing happened can be interpreted from the TRACE level logs.

I am using C# Selenium for automated testing, and after the most recent chromedriver update 89.0.4389.2300, Google chrome starts and crashes right away. The weirdest thing is that when I am running it on my local, everything works fine, but I am also using Azure pipelines to run my tests on a server. The server one gives me this:
OpenQA.Selenium.WebDriverException : unknown error: Chrome failed to start: crashed.
(unknown error: DevToolsActivePort file doesn't exist)
(The process started from chrome location C:\Program Files (x86)\Google\Chrome\Application\chrome.exe is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
I have googled around and tried things like adding chromeOptions.AddArgument("--no-sandbox") and chromeOptions.AddArguments("disable-dev-shm-usage") but nothing helps. Chrome on my server is updated to the correct version too. The tests run headless.
Anyone else is having this issue?
The error mentions that chromedriver could not bind to open debug port on running Chrome.
Possible cases I met with:
old version of Chrome browser or chromedriver - since some version the port has changed
wrong Chrome binary location (chromedriver is looking for C:\Program Files (x86)\Google\Chrome\Application\chrome.exe)
I created a very simple C# project to test Selenium and Chrome Driver, but when I run it, it gets stuck at the very first line, ie. creating ChromeDriver object.
I have set up as following:
.NET Core 3.1 console app (also tried .NET 4.7)
Installed Selenium.WebDriver 3.141.0 and Selenium.WebDriver.ChromeDriver 87.0.4280.8800.
My Chrome version is "Version 87.0.4280.88 (Official Build) (64-bit)". I have double-checked compatibility with Chrome and ChromeDriver.
Code:
using OpenQA.Selenium.Chrome;
namespace MyFirstSelenium
{
class Program
{
static void Main(string[] args)
{
ChromeDriver chrome = new ChromeDriver();
chrome.Navigate().GoToUrl("https://www.google.co.jp/");
}
}
}
visual studio screen
chromedriver.exe is copied to the debug folder as expected, so I assume the problem is neither compatibility nor path.
chromedriver
When I run the code, the result is an empty window with 'data' in the address bar. No error is thrown. I have searched for several hours and found some articles, but most of them are old and none of these answers led to success.
Any help is appreciated. Thank you.

New code
Works when I first execute "chromedriver.exe --verbose --log-path=chromedriver.log", but without it, it throws WebDriverException.
OpenQA.Selenium.WebDriverException: 'A exception with a null response was thrown sending an HTTP request to the remote WebDriver server for URL localhost:9515/session. The status of the exception was UnknownError, and the message was: No connection could be made because the target machine actively refused it. No connection could be made because the target machine actively refused it.'
var chromeOptions = new ChromeOptions();
chromeOptions.BrowserVersion = "87";
IWebDriver driver = new RemoteWebDriver(new Uri("http://localhost:9515"), chromeOptions);
Possibly a classic case of cyclic redundancy.
chrome is a reserved word, you may have to change the variable name to something else e.g. chromex. So your effective line of code will be:
ChromeDriver chromex = new ChromeDriver();
Additional Consideration
Consider the following aspects aswell:
Instead of using the ChromeDriver class use the IWebDriver interface.
IWebDriver driver = new ChromeDriver();
Instead of the partial url google.co.jp/ you need to pass the complete url through GoToUrl() as follows:
driver.Navigate().GoToUrl(#"https://www.google.co.jp/");
This is most likely a duplicate question, but in my looking around i couldnt find an answer that matches my question exactly.
I am using selenium and NUnit to run unit tests, due to circumstances I have not been working on it for a while, and now that I come back I get this error on all my chrome tests:
OneTimeSetUp: System.InvalidOperationException : session not created: This version of ChromeDriver only supports Chrome version 79 (SessionNotCreated)
I have updated the driver to make sure that wasn't the issue, but even using the version 83 one, I still get this same error.
The ChromeDriver in your Windows %PATH% is likely a different version. The updated driver you downloaded needs to be saved over top of the ChromeDriver in your path.
Open the command prompt
Type where ChromeDriver and press Enter.
Save the updated ChromeDriver in the folder specified in the output of the where command.
You should update the ChromeDriver in your project. It might be done via Tools -> NugetPages.
My Chrome browser is updated to version 78 and when I tried to execute any code of automation, it shows the error

Analysis
The first log message:

is part of the startup log when using ChromeDriver and is informative in nature.
You can find a detailed discussion in How do I protect the ports that chromedriver use?
The following log message:

I have fixed this issue of timeout / Connection reset by changing my code from:
public void AfterScenario(Scenario sc) {
driver.close();
driver.quit();
driver = null;
}
to:
public void AfterScenario(Scenario sc) {
driver.quit();
driver = null;
}
So basically I removed the driver.close() and this fixed my issue. I do not know why this is happening, but experts can explain more...
I had to update to the dev version of chrome 79 and the latest dev version of chromedriver to make it work. Although I've run against other issues with this version, so I don't know if its a good solution.
I have updated the latest selenium webdriver (v 3.4.0) installed and have latest firefox driver(0.15.0). I have these installed in a project which I am working on by "Manage Nuget Packages" option. Suddenly all of my tests are failing as it is not able to interact with any of the elements on firefox browser. To state about my issue, when I try the below simple tests on a google website
IWebDriver driver = new FirefoxDriver();
driver.Url = "https://www.google.com/";
var MyKeyWord = driver.FindElement(By.Id("lst-ib"));
MyKeyWord.SendKeys("Gmail");
it is failing with below exception.
An unhandled exception of type 'System.InvalidOperationException' occurred in WebDriver.dll
Additional information: Expected [object Undefined] undefined to be a string (IndexOutOfBounds)
I was searching on how to handle this problem and I found a solution as below:
driver = new FirefoxDriver(DRIVER_PATH);
But all my tests were executing without specifying these path in firefox earlier as firefox picks them when we install the required package using "Manage Nuget Packages" option. I am not sure why it started failing all of a sudden. Does someone have any suggestion on this?
Download latest geckodriver from https://github.com/mozilla/geckodriver/releases. Unzip it and put gecodriver file your system path. Restart (if needed) .
This link will help for setup : https://github.com/mozilla/geckodriver
I hope it will help.
There are two Chromedriver displays in NuGet manager - one driver for Chrome and other one is Selenium Google Chrome driver. You have to install both, then it works.
