<!-- Greeting --> Hi @cvrdev! I'm [Dosu](https://go.dosu.dev/dosubot) and Iām helping the superset team. <!-- Answer --> Your error is likely caused by a mismatch or missing configuration for the headless browser inside your Docker worker container. Superset relies on Selenium WebDriver (with Firefox/Chrome) for generating report screenshots, and the default Docker image does not include a browser or driver by default. The AttributeError about 'capabilities' usually means the WebDriver configuration is not matching what Selenium expects, or the browser/driver is missing or misconfigured [[source](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/config.py)]. **How to fix:** 1. **Install a headless browser and driver in your worker container.** The latest docs recommend using Playwright with Chrome, or you can use Firefox with geckodriver, or Chrome with chromedriver. Only the worker container needs the browser. Example Dockerfile snippets are available in the updated docs [[source](https://github.com/apache/superset/pull/34908)]. 2. **Check your `superset_config.py` for the correct WebDriver configuration.** For Firefox, the default config is: ```python WEBDRIVER_TYPE = "firefox" WEBDRIVER_CONFIGURATION = { "options": {"capabilities": {}, "preferences": {}, "binary_location": ""}, "service": {"log_output": "/dev/null", "service_args": [], "port": 0, "env": {}}, } WEBDRIVER_OPTION_ARGS = ["--headless"] ``` For Chrome, set: ```python WEBDRIVER_TYPE = "chrome" WEBDRIVER_OPTION_ARGS = [ "--force-device-scale-factor=2.0", "--high-dpi-support=2.0", "--headless", "--disable-gpu", "--disable-dev-shm-usage", "--no-sandbox", "--disable-setuid-sandbox", "--disable-extensions", ] ``` 3. **Verify the browser and driver are installed and accessible.** Enter your worker container and run `firefox --headless` and `geckodriver` (or `chromedriver` for Chrome) to confirm they start without errors [[source](https://github.com/apache/superset/pull/34908)]. 4. **If using the Docker dev environment, set `ALERT_REPORTS_NOTIFICATION_DRY_RUN = False`** in your config to actually send emails, not just simulate them [[source](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/docker/pythonpath_dev/superset_config.py)]. 5. **Restart your worker container** after making these changes. If you still see the AttributeError, double-check that your `WEBDRIVER_CONFIGURATION` matches the expected structure and that the browser/driver versions are compatible with your Selenium version [[source](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/utils/webdriver.py)]. More details and example Dockerfiles are in the updated documentation: https://github.com/apache/superset/pull/34908 Let me know if you need a specific example for your Dockerfile or config! <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
