Java, Selenium, Chrome - Unable to click button, even though it seems to be able to find it just fine

Question

I'm making a small bot for Cookie Clicker just to practice Selenium, and I have it working alright, the code is a mess, but that's not the problem, yet..
I have an issue accessing the options pane to load a savegame. My driver seems to be able to find the options button, but unable to click it.

private void loadGame() {
    System.out.println(driver.findElement(By.xpath("/html/body/div/div[2]/div[18]/div[1]/div[1]")).getText());
    driver.findElement(By.xpath("/html/body/div/div[2]/div[18]/div[1]/div[1]")).click();
}

It prints "Options", which is what leads me to believe it finds the element just fine, but throws an exception when I have it click in the next line

the print line is line 40, and the click line is line 41

Answer 1

Try using:

try{
 System.out.println(driver.findElement(By.xpath("/html/body/div/div[2]/div[18]/div[1]/div[1]")).getText());
    driver.findElement(By.xpath("/html/body/div/div[2]/div[18]/div[1]/div[1]")).click();
}catch(StaleElementReferenceException e){
 driver.findElement(By.xpath("/html/body/div/div[2]/div[18]/div[1]/div[1]")).click();
}

It usually solves the issue, if it doesn't try the example given by: How to avoid "StaleElementReferenceException" in Selenium?

Answer 2

You can join waiting

WebDriverWait wait = new WebDriverWait(driver, 30);
wait.until(ExpectedConditions.elementToBeClickable(By.xpath("/html/body/div/div[2]/div[18]/div[1]/div[1]")));
