"Nosuchwindowexception: No Such Window: Window Was Already Closed" While Switching Tabs Using Selenium and Webdriver Through Python3

I have a form that opens in a new tab when I click on it. When I try to navigate to that new tab, I keep getting a NoSuchWindowException. Code is pretty straightforward. 'myframe' is the frame within the new tab that the information will eventually get plugged into. Should I be waiting for something else?
from selenium import webdriver
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.ui import WebDriverWait, Select
from selenium.webdriver.common.by import By
from selenium.common.exceptions import TimeoutException, NoSuchElementException

url = *****
driver = webdriver.Chrome(executable_path = r'S:\Engineering\Jake\MasterControl Completing Pipette CalPM Forms\chromedriver')
driver.get(url)
wait = WebDriverWait(driver, 5)
window_before = driver.window_handles[0]
driver.find_element_by_id('portal.scheduling.prepopulate').click()
window_after = driver.window_handles[1]
driver.switch_to_window(window_after)
driver.switch_to_default_content()
wait.until(EC.frame_to_be_available_and_switch_to_it('myframe'))

As per your question and your code trials when you intend to navigate to a new tab you need to:
- Induce WebDriverWait while switching to the New Tab.
- Again when you intend to
switch()to the desired<iframe>you need to induce WebDriverWait again. - While you
switch()to the desired<iframe>try to use either ID, NAME, XPATH or CSS-SELECTOR of the desired<iframe>. Your own code with these simple modification will be as follows:
from selenium import webdriver from selenium.webdriver.support import expected_conditions as EC from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.common.by import By url = "your_url" driver = webdriver.Chrome(executable_path = r'S:\Engineering\Jake\MasterControl Completing Pipette CalPM Forms\chromedriver') driver.get(url) windows_before = driver.current_window_handle driver.find_element_by_id('portal.scheduling.prepopulate').click() WebDriverWait(driver, 5).until(EC.number_of_windows_to_be(2)) windows_after = driver.window_handles new_window = [x for x in windows_after if x != windows_before][0] # driver.switch_to_window(new_window) <!---deprecated> driver.switch_to.window(new_window) WebDriverWait(driver, 5).until(EC.frame_to_be_available_and_switch_to_it((By.ID,"myframe"))) # or By.NAME, By.XPATH, By.CSS_SELECTOR
Thanks Debanjan (and apologies for late response - just got back to office). I was able to fix this by using
While True:
try:
[navigate to the new frame, wait for a specific element to show up]
break
except (NoSuchWindowException, NoSuchElementException):
pass
I had not realized that when I clicked to open the form, another window opened very briefly in the background, and then closed. This increased the window_handles to 2, so doing anything relating to waiting for 2 window handles still kept throwing an error.
Please try to update your chrome version. The same error occurred for me, which happened in chrome 70, after an update to 91, it is ok.
