I have never experienced an error like this before. Is the website I'm visiting resistant to the use of automation tests?

Code:

public class DirectoryAutomation {

    public static void main(String[] args) throws IOException, InterruptedException {

        System.setProperty("webdriver.chrome.driver", "C:\\Users\\MartinErlic\\eclipse-workspace\\DirectoryAutomation\\libs\\chromedriver.exe");
        ChromeDriver driver = new ChromeDriver();
        driver.get("https://www.arivify.com/property/az/mesa");
        Thread.sleep(2000);
        driver.findElement(By.xpath("xpath=//div[@id='__layout']/div/div[2]/section/div/table/tbody/tr/td")).click();
    }
}

Exception:

Does this occur if you try other websites using this same code (Specifically using the same webdriver version and chrome version)?

Seeing this [1579544613.399][WARNING]: This version of ChromeDriver has not been tested with Chrome version 79.. Tells me that you're likely using incompatible versions of your driver.exe and chrome.

Seeing that you're using chrome version 79, you should fetch the chromedriver version that matches it https://chromedriver.chromium.org/downloads, which is 79.0.3945.36. You are using 78.0.3904.105 currently.

Even though the throw is happening on the get(url) method, which could make it seem like the website is contributing to this error, I believe this is coincidental and that the problem will occur on the first instruction to the browser, no matter which type that is.

Edit. This looks like a new issue. Verify that your xpath points to a valid element, and that the page is fully loading. For testing, I suggest trying to locate simpler xpath to a persistent part of the page near the root element, to verify that locating works generally. This exception suggests though that you're all set up, and that you need to start tuning to the site to get timing and locating working
