[Python] Selenium Headless vrs Non Headless. I can't get Selenium to set a field while using...

I saw I needed to add a window size however that did not fix my issue here is the working Non headless code

# _-_-_- Non Headless -_-_-_
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
import webbrowser

def GetFAAapdURL(APD):
driver = webdriver.Chrome()
driver.get("https://www.faa.gov/airports/runway_safety/diagrams/")
input_field = driver.find_element(By.ID, "ident") # Replace with actual ID
input_field.send_keys(APD)
input_field.send_keys(Keys.RETURN)
table = driver.find_element(By.XPATH, "//table") # Adjust XPath as needed
links = table.find_elements(By.TAG_NAME, "a")
for link in links:
href = link.get_attribute("href")
if href: # Ensure the href is not None
if "aeronav.faa" in href:
print(href)
return href

webbrowser.open(GetFAAapdURL("ATL"))


Abd now the Headless version

# _-_-_- Headless -_-_-_
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import Options
from selenium import webdriver
import webbrowser

def GetFAAapdURL_Headless(APD):
chrome_options = Options()
chrome_options.add_argument("--headless") # Run Chrome in headless mode
chrome_options.add_argument('--window-size=1920x1080')
driver = webdriver.Chrome(options=chrome_options)

driver.get("https://www.faa.gov/airports/runway_safety/diagrams/")
input_field = driver.find_element(By.ID, "ident")
input_field.send_keys(Keys.RETURN)
table = driver.find_element(By.XPATH, "//table") # Adjust XPath as needed
links = table.find_elements(By.TAG_NAME, "a")
for link in links:
href = link.get_attribute("href")
if href: # Ensure the href is not None
if "aeronav.faa" in href:
print(href)
return href

webbrowser.open(GetFAAapdURL_Headless("ATL"))


here is the line that errors

input_field = driver.find_element(By.ID, "ident")


I tried to minimize the window and that has a flashing of the window at start and still errors. So not a great solution.
