selenium.WebDriverException: chrome not reachable

Question

I have a C++ application application.exe, which uses a CEF browser (chrome embedded framework) as the UI.

For this UI I want to develop automated tests with Selenium. Usually I control Selenium via Java.

below is the stack trace I'm getting:

Starting ChromeDriver 91.0.4472.101 (af52a90bf87030dd1523486a1cd3ae25c5d76c9b-refs/branch-heads/4472@{#1462}) on port 36815
Only local connections are allowed.
Please see https://chromedriver.chromium.org/security-considerations for suggestions on keeping ChromeDriver safe.
ChromeDriver was started successfully.

My code snippet:

System.setProperty("webdriver.chrome.driver", "C:\\Users\\Administrator\\Desktop\\chromedriver_win32\\chromedriver.exe");
        
        
    ChromeOptions options = new ChromeOptions();
        
    options.setBinary(<cef_workflow_path>);
        
WebDriver chDriver = new ChromeDriver(options);
    
    
    
     
sleep(3000);
    
chDriver.findElement(By.id("EmailPage-EmailField"));
       
WebElement email = chDriver.findElement(By.id("EmailPage-EmailField"));
         
System.out.println(email.isDisplayed());
       
email.clear();
     
email.sendKeys(userName);

Answer 1

I see you truing to access web element on the web page before you passed an URL to the driver.
You need first to

chDriver.get(yourURLLink);

and only after that, when the page is loaded try accessing the elements with

chDriver.findElement(By.id("EmailPage-EmailField"));

etc.

Answer 2

Can you check with this, I hope it will work for you

ChromeOptions option = new ChromeOptions();
    
    option.addArguments(new ArrayList<String>() {
        {
            add("--no-sandbox");
            add("--disable-gpu-sandbox");
            
        }
    });
    
    WebDriver driver = new ChromeDriver(option);
