i'm new to this Selenium grid.. my node is default registered on Win10 platform.. so it is executing the script without any issue. But when i tried to run on Other than Win10 it is getting failed. can someone please help me how to resolve this. i reviewed all the solutions available in internet but i'm not able to resolve it.

Code

  baseURL = "http://demo.guru99.com/test/guru99home/";

         nodeURL = "http://192.168.1.4:4444/wd/hub";

         ChromeOptions options=new ChromeOptions();

         DesiredCapabilities cap=DesiredCapabilities.chrome();

         cap.setPlatform(Platform.LINUX);

         options.merge(cap);

         driver = new RemoteWebDriver(new URL(nodeURL), options);

if i need to add the capabilities for the other platforms where i have to add those capabilities.

This one solved my problem.

java -jar "C:UsersDELLDesktopSelenium Gridselenium-server-standalone-3.141.5.jar" -role node -hub http://*.*.*.*:PortNumber/grid/register -port 5557 -browser "browserName=chrome,platform=LINUX"

note: Place your Ip address in place of " * "

and also check the node URL Port number.
