Not able to launch firefox browser using selenium, SeleniumGrid failing with: org.openqa.selenium.WebDriverException: Error forwarding the new session cannot find : Capabilities

[Keshav]

I am using : java:1.8 Selenium: 3.141.59 jar Gecko driver version: 0.25.0 Firefox version : 69.0.1 OS: Windows 10

start java -jar C:/eclipse-workspace/Selenium_Grid/Config/selenium-server-standalone-3.141.59.jar -role hub

start java -Dwebdriver.gecko.driver=D:/Selenium/geckodriver-v0.25.0-win64/geckodriver.exe -jar C:/eclipse-workspace/Selenium_Grid/Config/selenium-server-standalone-3.141.59.jar -role node -hub http://localhost:4444/grid/register -port 5559 -maxSession 5

public static RemoteWebDriver getBrowserDriver(final String browser)
        throws MalformedURLException {
    return new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"),
            getBrowserCapabilities(browser));
}

private static DesiredCapabilities getBrowserCapabilities(
        final String browserType) throws MalformedURLException {
    switch (browserType.toLowerCase()) {
    case "firefox":
        System.out.println("Opening firefox driver");
        DesiredCapabilities capabilities = DesiredCapabilities.firefox();
		capabilities.setVersion("69.0.1");
        capabilities.setPlatform(Platform.WIN10);       
        return capabilities;
    }
}
