Getting HTTP 500 errors despite both servers running

[cortosi]

I'm pretty new to Windows desktop automation and I'm stuck on what should be a basic setup.

Background & Context

I just started learning Windows desktop automation and discovered that WinAppDriver became obsolete starting with Appium 5.0.0. From what I understand, Appium now acts as a proxy toWinAppDriver, so both services need to be running simultaneously. This is where my problems begin.

Since both Appium and WinAppDriver try to use port 4723 by default, I'm running:

• Appium Server: on port 4723 (default)
• WinAppDriver: on port 4724 (to avoid conflicts)

namespace CalculatorTest
{
    public class CalculatorSession
    {
        private const string AppiumServerUrl = "http://127.0.0.1:4723/";
        private const string CalculatorID = "Microsoft.WindowsCalculator_8wekyb3d8bbwe!App";

        protected static WindowsDriver session;

        public static void Main()
        {
            AppiumOptions appiumOptions = new AppiumOptions
            {
                App = CalculatorID,
                PlatformName = "Windows",
                AutomationName = "Windows"
            };

            appiumOptions.AddAdditionalAppiumOption("appium:wadUrl", "http://127.0.0.1:4724");

            session = new WindowsDriver(new Uri(AppiumServerUrl), appiumOptions);

            Assert.IsNotNull(session);
            Assert.IsNotNull(session.SessionId);

            session.Manage().Timeouts().ImplicitWait = TimeSpan.FromSeconds(1.5);
        }
    }
}

The Problem - Two Different Errors

Error from my C# Application:

this url is wrong
private const string AppiumServerUrl = "http://127.0.0.1:4723/";

for appium
private const string AppiumServerUrl = "http://127.0.0.1:4723/wd/hub";

for windows application driver:
private const string AppiumServerUrl = "http://127.0.0.1:4724/";

@cortosi have you managed to solve the problem? I am also getting 500 error when I am trying to call to driver.page_source
