Selenium SessionNotCreatedException with FirefoxDriver

Question

I am working on an application for my job that extracts data from our web application. I am trying to connect to the website with Selenium, but am receiving a SessionNotCreatedException . Here's what is causing the issue in an isolated environment:

public void testDriver() {
    System.setProperty("webdriver.gecko.driver", "C:\\data\\brandonw\\Desktop\\Docs\\geckodriver.exe");
    WebDriver driver = new FirefoxDriver();
    driver.get("http//user:pass@flag.60north.net/");
}

I originally thought this was an issue from the authentication prompt from our webpage upon initial connection. With Jsoup, I would normally just use a basic authentication header, but with Selenium, I found that putting the user and pass in the url in the above format was the solution. Authentication doesn't seem to be the issue.

The next potential cause I found online was that my Firefox, Selenium, or Geckodriver (any combination of the three) were not up to date. Here is what I am currently working with:

Firefox: v58 Selenium: v3.8.1 geckodriver: 0.19.1

From what I read on github, geckodriver 0.19.0 supports Firefox 55.0+ and Selenium 3.5+, so it doesn't seem to be a version issue either. I'm now stumped with what this could be. My stack trace is as follows:

Thanks in advance for any help you guys might provide!

Edit: Just as an additional thought, I tried both the 32bit and 64bit of geckodriver as well.

Answer 1

With all the binaries Firefox: v58 , Selenium: v3.8.1 and geckodriver: 0.19.1 in proper configuration and looking at the error as :

10:         0x773859cd - BaseThreadInitThunk
    at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source)

BaseThreadInitThunk is the initialization function run during initialization/creation of a new thread. This is the function that will call the start address of your thread, which means :

• BaseThreadInitThunk is used only to execute your thread's function.
• You will find its address somewhere on the stack of a newly created thread.
• It is a function to breakpoint if you want to break in newly created threads.

Hence, I suppose you are missing a mandatory import among one of the following and you have to add both of them :

• import org.openqa.selenium.WebDriver;
• import org.openqa.selenium.firefox.FirefoxDriver;
