AutoSetUpConfiguredDrivers occasionally throws an 'Index out of range" Exception

Question

Here's the content of my GlobalSetup - occasionally when I run, the call to AutoSetUpConfiguredDrivers throws an exception:

System.ArgumentOutOfRangeException: 'Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')'

        EdgeOptions Options = new EdgeOptions();
            Options.AddArgument("window-size=1600,900");
            Options.AcceptInsecureCertificates = true;

        EdgeOptions HeadlessOptions = new EdgeOptions();
            HeadlessOptions.AddArgument("headless");
            HeadlessOptions.AddArgument("window-size=1600,900");
            HeadlessOptions.AcceptInsecureCertificates = true;

        AtataContext.GlobalConfiguration
            .UseChrome().WithArguments("ignore-certificate-errors", "window-size=1600,900")
            .UseChrome().WithArguments("ignore-certificate-errors", "window-size=1600,900", "headless").WithAlias("chrome-headless")
            .UseFirefox().WithGlobalCapability("acceptInsecureCerts", true).WithArguments("--width=1600").WithArguments("--height=900")
            .UseFirefox().WithGlobalCapability("acceptInsecureCerts", true).WithArguments("--width=1600").WithArguments("--height=900").WithArguments("--headless").WithAlias("firefox-headless")
            .UseEdge().WithOptions(Options)
            .UseEdge().WithOptions(HeadlessOptions).WithAlias("edge-headless")
            .UseCulture("en-US")
            .AddScreenshotFileSaving()
            .UseNUnitTestName()
            .UseNUnitTestSuiteName()
            .UseNUnitTestSuiteType()
            .UseNUnitAssertionExceptionType()
            .UseNUnitAggregateAssertionStrategy()
            .UseNUnitWarningReportStrategy()
            .AddNUnitTestContextLogging()
                .WithMinLevel(LogLevel.Info)
                .WithoutSectionFinish()
            .LogNUnitError()
            .TakeScreenshotOnNUnitError("Test Failure")
            .OnCleanUpAddArtifactsToNUnitTestContext();            

        //DriverSetup.AutoSetUp(BrowserNames.Edge);
        AtataContext.GlobalConfiguration.AutoSetUpConfiguredDrivers();

If I uncomment the DriverSetup line, I never see the error. Using Atata 1.13.0, Atata.WebDriverSetup 1.2.0 and Selenium 4.0.0 - any ideas?

Could you please share the StackTrace of the exception? We need it to understand from where exactly this exception was thrown. — Yevgeniy Shunevych, Oct 22 '21 at 07:52
Added the stack trace to the original post - it's too big for a comment — Steve Gray, Oct 22 '21 at 13:51

There was a thread synchronization bug in Atata.WebDriverSetup v1.2.0. Thanks for reporting it. It should be fixed now in Atata.WebDriverSetup v1.2.1. Please update the package and verify that this error doesn't reproduce.
