SessionNotCreatedException: Could not start a new session. Unable to parse remote response error using SeleniumGrid

I am implementing selenium grid and the capability to launch the tests using the RemoteWebDriver. I am using docker standalone image.
Below is my code
public void setUp() throws MalformedURLException {
ChromeOptions options = new ChromeOptions();
options.addArguments("--no-sandbox");
options.addArguments("--headless");
options.addArguments("--disable-dev-shm-usage");
WebDriver driver = new RemoteWebDriver(new URL("http://localhost:4444"),options);
driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(20));
driver.get("www.google.com");
driver.manage().window().maximize();
}
Command:
docker run -d -p 4444:4444 -p 7900:7900 --shm-size="2g" selenium/standalone-chrome:latest
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
1f810511cbe2 selenium/standalone-chrome:latest "/opt/bin/entry_poin…" 9 seconds ago Up 7 seconds 0.0.0.0:4444-\>4444/tcp, 0.0.0.0:7900-\>7900/tcp, 5900/tcp modest_keller
I have also added selenium-java, selenium-manager and testing dependencies in pom.xml. I am using:
Java 11
Selenium 4.8.0
Selenium Manager 4.8.0
Chrome version 109.0.5414.119
IDE IntelliJ
MacOS
I am getting below errors:
org.openqa.selenium.SessionNotCreatedException: Could not start a new session.

Add /wd/hub at the end of the your driver URL as:
WebDriver driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), options);
or
WebDriver driver = new RemoteWebDriver(new URL("http://127.0.0.1:4444/wd/hub"), options);

new session request for webdriver should contain a location header or an 'application/json;charset=UTF-8' response body with the session ID [duplicate]

First of all You are using a little bit old version of gecko driver. The newest from: https://github.com/mozilla/geckodriver/releases
Then You need to set up system property with:
File gecko = new File("C:/Users/admin/Downloads/geckodriver-v0.19.0-win32/geckodriver.exe");
System.setProperty("webdriver.gecko.driver", gecko.getAbsolutePath());
If You really want to use marionette check answers on: Difference between webdriver.firefox.marionette & webdriver.gecko.driver

I haved this error for 2 days, the solution for me was in Set.Plataform put Platafor.ANY or Plataform.Windows because Plataform.WIN10 not worked, marionette wasn't necessary and I added and neether works, only works this. I hope this helps someone else:
public class Main {
public static RemoteWebDriver driver;
public static void main(String[] args) throws MalformedURLException {
System.setProperty("webdriver.gecko.driver", "D:/Lib/geckodriver.exe");
DesiredCapabilities desiredCapabilities = new DesiredCapabilities().firefox();
desiredCapabilities.setPlatform(Platform.ANY);
desiredCapabilities.setBrowserName("firefox");
driver = new RemoteWebDriver(new URL("http://172.20.19.182:5557/wd/hub"), desiredCapabilities);
driver.navigate().to("http://www.google.com");
driver.findElementByName("q").sendKeys("execute automation");
driver.findElementByName("q").sendKeys(Keys.ENTER);
driver.close();
// write your code here
}
}

You can also try using double \\ in the path of the geckodriver.
Also instead of using :
System.setProperty(
"webdriver.firefox.marionette",
"C:/Users/admin/Downloads/geckodriver-v0.11.1-win32/geckodriver.exe");
Can you try using
System.setProperty(
"webdriver.gecko.driver",
"C:\\Users\\admin\\Downloads\\geckodriver-v0.11.1-win32\\geckodriver.exe");

Title : Problem Resolved
Solution Accepted :
- Use latest version of gecko driver
Code Used
- System.setProperty("webdriver.gecko.driver","C:\Marionette\geckodriver_1.exe" );

Java try-catch not catching exception

I have the following method:
private void checkIfLoggedIn() {
try{
try {
new WebDriverWait(driver, 10)
.until(ExpectedConditions.visibilityOfElementLocated(
By.cssSelector("a[href*='score']")));
}
catch (WebDriverException e) {
}
loggedInState = 2;
}
catch (TimeoutException e) {
loggedInState = -1;
}
}
Simply put, this method's job is to wait until the webpage finishes loading the logged-in pa
ge, and let the rest of the code know by changing a variable. This code works perfectly the vast majority of the time, however if the driver is closed (by another thread) before it finishes, it crashes. I'm perfectly fine with the code stopping - If the webpage has closed it has most likely finished it's task (or crashed for a different reason). The problem is that the error log (posted below) won't go away. I'v even tried something as broad as catch (Exception e)in order to catch any possible exception, but the crashlog won't go away. Any Advice would be appreciated!
EDIT: Thanks to #jdigital, I discovered that the code was in fact catching the exceptions, however that was masked by Selenium outputting it's own exceptions. Any advice on how to have selenium stop outputting errors would be appreciated!

You should be able to set Selenium's Logging Preferences to customize the exception output.
EDIT:
Perhaps the instructions at the above referenced link aren't too helpful.
It looks like Selenium uses the standard Java logger interface. Get hold of the RemoteWebDriver object and then turn off its logging via setLogLevel(java.util.logging.Level.OFF).
For another alternative, the FirefoxDriver allows stdout/stderr to be redirected to a file. This has the advantage of allowing you to inspect the output should you need to do so; otherwise, you can just overwrite it or delete it.

Selenium HtmlUnit Driver Exception

I'm using JUnit, Selenium WebDriver and try to make some tests with HtmlUnit and http://vk.com site but fail.
It looks like FirefoxDriver works great for me.
Here is code:
#Before
public void setUp() {
DesiredCapabilities capabilities = DesiredCapabilities.htmlUnit();
capabilities.setBrowserName("Mozilla/5.0 (X11; Linux x86_64; rv:24.0) Gecko/20100101 Firefox/24.0");
capabilities.setVersion("24.0");
capabilities.setJavascriptEnabled(true);
driver = new HtmlUnitDriver(capabilities);
driver.manage().timeouts()
.implicitlyWait(Integer.parseInt(TIMEOUT), TimeUnit.SECONDS);
driver.get("http://vk.com");
}
#Test
public void SomeTest() {
/* LoginPage - described class in PageObject traditions */
LoginPage start = new LoginPage(driver);
LOG.info(driver.getPageSource());
//...
}
When I start it I get the an exception:
org.openqa.selenium.WebDriverException: com.gargoylesoftware.htmlunit.ScriptException: Exception invoking setInnerHTML

Any suggestions?
ps. This is black-box testing I've no access to change internal code on site.

Different drivers have different ways to handle javascript.
Htmlunit uses Rhino and firefox-driver uses Firefox's default javascript handler and hence, you see different results with different drivers.

Replace htmlUnit() with firefox() for your fix.
DesiredCapabilities capabilities = DesiredCapabilities.firefox()
capabilities.setBrowserName("Mozilla/5.0 (X11; Linux x86_64; rv:24.0) Gecko/20100101 Firefox/24.0");
capabilities.setVersion("24.0");
driver = new HtmlUnitDriver(capabilities);
