org.openqa.grid.common.exception.GridException: невозможно извлечь возможности из запроса

Когда я использую удаленный веб-драйвер для создания экземпляра, я отлично получаю возвращаемый объект.

Но вместо remotewebdriver, если я использую AndroidDriver, я получаю следующую ошибку. Пожалуйста, помогите.

Вот что говорит трассировка стека:

Caused by: java.lang.IllegalArgumentException: Illegal key values seen in w3c capabilities: [platform, version]

Я использую приведенный ниже код.

RemoteWebDriver getDriver(String appName, String appPackage, String appActivity) {
    DesiredCapabilities androidDcap = DesiredCapabilities.android();
    if (appName.equalsIgnoreCase("YMCA"))
        androidDcap.setCapability(MobileCapabilityType.AUTOMATION_NAME, "UiAutomator2");
    androidDcap.setCapability(MobileCapabilityType.PLATFORM_NAME, "Android");
    androidDcap.setCapability(MobileCapabilityType.BROWSER_NAME, "");
    androidDcap.setCapability(MobileCapabilityType.DEVICE_NAME, "Altitude");
    androidDcap.setCapability(MobileCapabilityType.CLEAR_SYSTEM_FILES, true);
    androidDcap.setCapability("autoGrantPermissions", "true");
    androidDcap.setCapability(MobileCapabilityType.NO_RESET, true);
    androidDcap.setCapability(MobileCapabilityType.FULL_RESET, false);
    androidDcap.setCapability(AndroidMobileCapabilityType.NO_SIGN, true);
    androidDcap.setCapability(AndroidMobileCapabilityType.AUTO_GRANT_PERMISSIONS, true);
    androidDcap.setCapability(AndroidMobileCapabilityType.APP_WAIT_DURATION, 60);
    androidDcap.setCapability("newCommandTimeout", 60);
    androidDcap.setCapability("appPackage", appPackage);
    androidDcap.setCapability("appActivity", appActivity);
    try {
        if (System.getProperty("location").equalsIgnoreCase("local")) {
            driver = new RemoteWebDriver(new URL("http://127.0.0.1:4651/wd/hub"), androidDcap);
        } else {
            driver = new RemoteWebDriver(new URL(PropertyHelper.getProperties("REMOTE_HUB_URL")), androidDcap);
        }
    } catch (Exception e) {
        logger.error("Driver instantiating failed", e);
    }
    driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
    return driver;
}
