To address the Selenium TimeoutException when waiting for chart containers to draw in Superset, consider the following steps:

1. Increase Timeout Duration: Adjust the self._screenshot_locate_wait to allow more time for the chart containers to become visible. You can set this in your superset_config.py:

   SCREENSHOT_LOCATE_WAIT = 30  # Increase this value as needed
   SCREENSHOT_LOAD_WAIT = 60

2. Check Element Selectors: Verify that the class names used in By.CLASS_NAME, "chart-container" are correct and match the elements on the page.

3. Configure Selenium WebDriver: Ensure your Selenium WebDriver is properly configured. Add these configurations to your superset_config.py:

   WEBDRIVER_TYPE = 'chrome'
   WEBDRIVER_OPTION_ARGS = [
       '--headless',
       '--no-sandbox',
       '--disable-gpu',
       '--disable-dev-shm-usage',
       '--disable-setuid-sandbox',
       '--start-maximized'
   ]

4. Ensure Environment Setup: Make sure Chrome/Chromium and ChromeDriver are installed, the WebDriver has proper permissions, and there is sufficient memory available.

5. Handle Loading Elements: Wait for loading elements to disappear before taking the screenshot:

   try:
       WebDriverWait(driver, self._screenshot_load_wait).until_not(
           EC.presence_of_all_elements_located((By.CLASS_NAME, "loading"))
       )
   except TimeoutException:
       raise

6. Account for Animation Delays: Add a wait time for animations to complete:

   selenium_animation_wait = current_app.config["SCREENSHOT_SELENIUM_ANIMATION_WAIT"]
   sleep(selenium_animation_wait)

These adjustments should help resolve the TimeoutException by allowing more time for elements to load and ensuring the correct elements are targeted ^[1][2].

@dosu
I already have

WEBDRIVER_TYPE= "chrome"
WEBDRIVER_OPTION_ARGS = [
"--force-device-scale-factor=2.0",
"--high-dpi-support=2.0",
"--headless",
"--disable-gpu",
"--disable-dev-shm-usage",
# This is required because our process runs as root (in order to install pip packages)
"--no-sandbox",
"--disable-setuid-sandbox",
"--disable-extensions",
]
WEBDRIVER_CONFIGURATION : {"service_log_path": "/dev/null" }

    SCREENSHOT_LOCATE_WAIT = 100
SCREENSHOT_LOAD_WAIT = 600

any changes more to do? @dosu
