Selenium WebDriver hangs when loading dynamic content in a React application using Chrome 120

I'm following best practices but I'm working with an scenario where my Selenium WebDriver tests hang indefinitely when trying to load a page with dynamic content in a React application using Chrome 120. The page includes components that fetch data asynchronously, and I suspect the WebDriver might be trying to interact with elements before they are fully rendered. I have tried waiting for elements to appear using both `WebDriverWait` and implicit waits, but the scenario continues. Hereโ€™s a snippet of the code Iโ€™m using: ```python from selenium import webdriver from selenium.webdriver.common.by import By from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC # Initialize WebDriver options = webdriver.ChromeOptions() options.add_argument('--headless') # Run in headless mode driver = webdriver.Chrome(options=options) # Navigate to the page driver.get('https://example.com/page-with-dynamic-content') try: # Waiting for a specific element to be present element = WebDriverWait(driver, 10).until( EC.presence_of_element_located((By.CSS_SELECTOR, '.dynamic-content')) ) print('Element found:', element.text) except Exception as e: print('behavior:', e) finally: driver.quit() ``` When I run this code, the script hangs at the `WebDriverWait` call, and I see no errors in the console. The dynamic content takes about 5-7 seconds to load in a browser. I've also tried adjusting the wait time to 15 seconds, but that didnโ€™t resolve the scenario. Additionally, I verified that the CSS selector is correct and the element appears in the DOM after the data is fetched. Has anyone else faced a similar scenario with Selenium and dynamic content loading in a React app? Any guidance on how to handle this would be appreciated.
