Menu
I am running chromedriver to try and scrape some data off of a website. Everything works fine without the headless option. However, when I add the option the webdriver takes a very long time to load the url, and when I try to find an element (that is found when run without --headless), I receive an error.
Using print statements and getting the html after the url "loaded", I find that there is no html, it's empty (See in output below).
class Fidelity:
def __init__(self):
self.url = 'https://eresearch.fidelity.com/eresearch/gotoBL/fidelityTopOrders.jhtml'
self.options = Options()
self.options.add_argument("--headless")
self.options.add_argument("--window-size=1500,1000")
self.driver = webdriver.Chrome(executable_path='.\\dependencies\\chromedriver.exe', options = self.options)
print("init")
def initiate_browser(self):
self.driver.get(self.url)
time.sleep(5)
script = self.driver.execute_script("return document.documentElement.outerHTML")
print(script)
print("got url")
def find_orders(self):
wait = WebDriverWait(self.driver, 15)
data= wait.until(ec.visibility_of_element_located((By.CSS_SELECTOR, '[id*="t_trigger_TSLA"]'))) #ERROR ON THIS LINE
This is the entire output:

<html><head></head><body></body></html>

I have tried finding the answer to this through google but none of the suggestions work. Is anyone else having this issue with certain websites? Any help appreciated.
This script still does not work unfortunately, the webdriver is not loading the page correctly for some reason while headless, even though everything works perfectly without running this using the headless option.

For anyone in the future who is wondering the fix to this, some websites just don't load correctly with the headless option of chrome. I don't think there is a way to fix this. Just use a different browser (like firefox). Thanks to user8426627 for this.
