GitHub user dosubot[bot] added a comment to the discussion: How can I integrate Superset charts with PlayWright to ensure that all charts and data on the page are fully rendered and there are no unexpected errors before taking a screenshot?
<!-- Answer --> Your validation method closely matches Superset’s own Playwright/Selenium screenshot automation and covers all the critical steps: waiting for the dashboard and chart containers, waiting for loading elements to disappear, checking for chart content, waiting for animation delays, detecting error alerts (including 502/503/504), and retrying on temporary failures. This is the recommended approach for ensuring charts are fully rendered before screenshots and for handling transient server load issues in Superset ([reference](https://github.com/apache/superset/blob/master/superset/utils/webdriver.py)). However, no frontend automation can fully “solve” backend server load or persistent 502 errors—your code can only detect, retry, and fail gracefully if the backend cannot deliver data. For best results, make sure your Superset backend is tuned: increase timeouts like `SCREENSHOT_LOCATE_WAIT` and `SCREENSHOT_LOAD_WAIT`, enable HTTP retries (`SUPERSET_CLIENT_RETRY_ATTEMPTS` etc.), and optimize your database and proxy settings ([reference](https://github.com/apache/superset/blob/master/superset/config.py)). For very large dashboards, consider increasing your max wait times and resource limits. If you want to go even further, you could check for the presence of login screens (to catch authentication/session issues), and monitor resource usage on your Superset server during heavy loads. But overall, your method is robust and aligns with Superset’s best practices for screenshot and chart completeness validation. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
