How to Send Text in javascript's basic auth

[jt4000]

Goal:
Add text "Accepting the alert" in the textbox from javascript's basic auth dialog and then click button "OK".

Problem:
When I execute the code "driver.SwitchTo().Alert().SendKeys("Accepting the alert");" I retrieve a error message that is "Missing 'value' parameter (IndexOutOfBounds)".

Can't find a relevant answer to my problem. Tried to solve this case but it didn't go so well.

Info:
*Using Visual Studio and Selenium for C# code.

Thank you!

FirefoxDriverService firefoxDriverService = FirefoxDriverService.CreateDefaultService(@"C:\\Test3", "geckodriver.exe");
    firefoxDriverService.FirefoxBinaryPath = @"C:\Program Files (x86)\Mozilla Firefox\firefox.exe";


    var driver = new FirefoxDriver(firefoxDriverService);
    driver.Navigate().GoToUrl("http://toolsqa.wpengine.com/handling-alerts-using-selenium-webdriver/");
    driver.Manage().Window.Maximize();
    IWebElement element = driver.FindElement(By.XPath("//button[contains(@onclick,'promptConfirm')]"));

    try
    {
        IJavaScriptExecutor executor = (IJavaScriptExecutor)driver;

        executor.ExecuteScript("arguments[0].click();", element);
    }
    catch (InvalidOperationException eee)
    {
        int dd = 23;

    }


    driver.SwitchTo().Alert().SendKeys("Accepting the alert");
