I have run into an issue when setting up RemoteWebDriver (in this case with Browserstack) running automation using Selenium Webdriver.

My exact code has worked previously, which indicated that this may be a versioning issue, but after updating my version of selenium to the latest I still see the error. Selenium version 3.141.0

Code as follows (This is taken directly from Browserstack docs, with slight modifications, and differs from my actual code, but for illustration it is simpler and my error is identical)

class Program

{

    static void Main(string args)

    {

        IWebDriver driver;

        var chromeOptions = new ChromeOptions();

        chromeOptions.AddAdditionalCapability("browserstack.user", "xxxxxxxxxxxxxx");

        chromeOptions.AddAdditionalCapability("browserstack.key", "xxxxxxxxxxxxxx");

        chromeOptions.AddAdditionalCapability("browser", "Chrome");

        chromeOptions.AddAdditionalCapability("browser_version", "62.0");

        chromeOptions.AddAdditionalCapability("os", "Windows");

        chromeOptions.AddAdditionalCapability("os_version", "10");

        chromeOptions.AddAdditionalCapability("resolution", "1024x768");

        driver = new RemoteWebDriver(new Uri("http://hub.browserstack.com/wd/hub/"), chromeOptions);



        driver = new RemoteWebDriver(

          new Uri("http://hub-cloud.browserstack.com/wd/hub/"), chromeOptions

        );

        driver.Navigate().GoToUrl("http://www.google.com");

        Console.WriteLine(driver.Title);



        IWebElement query = driver.FindElement(By.Name("q"));

        query.SendKeys("Browserstack");

        query.Submit();

        Console.WriteLine(driver.Title);



        driver.Quit();

    }

}

Regardless of the options, I get the same error every time at the point of initialising the RemoteWebDriver

driver = new RemoteWebDriver(new Uri("http://hub.browserstack.com/wd/hub/"), chromeOptions);



System.InvalidCastException: 'Unable to cast object of type 'System.String' to type 'System.Collections.Generic.Dictionary`2[System.String,System.Object]'.'

The browserstack docs suggest using the now obsolete DesiredCapabilities class rather than DriverOptions, but I have tried both with the same error, and looking at RemoteWebDriver source, DriverOptions is a valid parameter within the various constructors.

There is probably something I am missing, but thought it would be worth posting to see if anyone has seen similar issues or any suggestions.

Thanks in advance
