what version of selenium are you using?

looks like it was resolved in #7390 for alpha-version, but stable is still suffering from this

I use 3.141.0. But yesterday i used new 4.0.0 alfa 03 version, but i got an error ' Message: System.IO.FileNotFoundException : Could not load file or assembly 'WebDriver, Version=4.0.0.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified. Stack Trace: PageObject.ctor() POLogin.ctor()' I guess it connected with SeleniumExtras.PageObjects 2020 թ. հնվ 9, հնգ, 17:49 cath3r0 <notifications@github.com> օգտատերը գրել է՝

I've upgraded Selenium Webdriver/Support version to 4.0.0-alpha04, but now there are new errors

Thank you for providing the details and the updates. I attempted to re-create the issue as follows.

Reproduced using the code sample below:

namespace SeleniumClient
{
    public class LogTypeError
    {
        private ChromeDriver driver;

        [SetUp]
        public void Setup()
        {
            ChromeOptions options = new ChromeOptions();
            options.SetLoggingPreference(LogType.Browser, LogLevel.All);

            ChromeDriverService service = ChromeDriverService.CreateDefaultService("path", "chromedriver");
            service.LogPath =  "path/chromedriver.log";
            service.EnableVerboseLogging = true;

            driver = new ChromeDriver(service, options);

        }

        [Test]
        public void logTypeErrorTest()
        {
            driver.Url = "http://www.yahoo.com";
            var logEntry = driver.Manage().Logs.GetLog(LogType.Browser);
            Assert.NotZero(logEntry.Count);
            driver.Quit();
        }
    }
}

Result
The test passes

Environment
OS: MacOS High Sierra
Browser: Chrome
Browser version: 89.0.4389.114
Browser Driver version: ChromeDriver 89.0.4389.23
Language Bindings version: 4.0.0-beta2

I would recommend upgrading to the latest version 4.0.0-beta2 and check if the problem still persists. Thank you!
