RemoteWebDriver throws “org.openqa.selenium.SessionNotCreatedException: Unable to create new remote session”

问题

I'am trying to run a simple code from hub to node, hub and node connections are successful.

While executing the program I am getting the exception

org.openqa.selenium.SessionNotCreatedException

Chrome driver path which I have mentioned is a share path that can be accessible from the node machine.

Chrome Version: 58.0.3029.110
Chrome Driver Version: 2.9

Both Hub and Node are remote machines.

Below is the code used:

public static void main(String[] args) throws MalformedURLException {

    WebDriver driver;
    System.setProperty("webdriver.chrome.driver", "Q:\\xxxxx\\chromedriver.exe");
    DesiredCapabilities dc = new DesiredCapabilities();
    dc.setBrowserName("chrome");
    dc.setPlatform(Platform.VISTA);
    driver = new RemoteWebDriver(new URL("http://10.xx.xxx.xx:5566/wd/hub"), dc); //node url
    driver.get("https://www.google.com");

}

Below is the console message:

Exception in thread "main" org.openqa.selenium.SessionNotCreatedException: Unable to create new remote session. desired capabilities = Capabilities [{browserName=chrome, platform=VISTA}], required capabilities = Capabilities [{}]

Here is the Answer to your Question:

As you have used the following command to start the Selenium Grid Hub:

 java -jar selenium-server-standalone-3.4.0.jar -role hub -port 4123

To execute your code block through chromedriver.exe and Google Chrome Browser you can consider to start the Selenium Grid Node on port 5566 through this command:

java -Dwebdriver.chrome.driver=chromedriver.exe -jar selenium-server-standalone-3.4.0.jar -role node -hub http://localhost:4123/grid/register -port 5566

Access the Selenium Grid Hub Console through <IP_of_GridHub>:4123/grid/console to see the Node being registered.
