<!-- Answer --> I found a similar closed issue regarding bar charts not rendering properly in dashboard emails, but no solution was found in the comments. You can view the issue [here](https://github.com/apache/superset/issues/14351) <sup>[[1]](https://github.com/apache/superset/issues/14351)</sup>. For troubleshooting issues with chart rendering in Superset email reports, you can follow these steps: 1. **Confirm Feature Flag and Permissions**: Ensure the `ALERT_REPORTS` feature flag is enabled in your configuration file. Verify that your configuration file is being loaded correctly by enabling another feature flag and checking its effect. Log in as an admin user to ensure you have adequate permissions. 2. **Check Celery Worker Logs**: Examine the logs of your Celery worker for any errors or issues. In a Docker Compose deployment, use a command like `docker logs superset_worker --since 1h` to view recent logs. 3. **Verify Web Browser and WebDriver Installation**: Ensure that the headless browser (Firefox or Chrome) and the corresponding WebDriver are correctly installed and configured. If you can send a chart as CSV or text but not as PNG, the issue might be with the browser setup. Test the installation by running `firefox --headless` and `geckodriver` in the Superset worker environment. 4. **Send a Test Email**: Test your email configuration by sending a test email. Use the following Python script to verify the SMTP settings: ```python import smtplib from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText from_email = '[email protected]' to_email = '[email protected]' msg = MIMEMultipart() msg['From'] = from_email msg['To'] = to_email msg['Subject'] = 'Superset SMTP config test' message = 'It worked' msg.attach(MIMEText(message)) mailserver = smtplib.SMTP('smtpmail.example.com', 25) mailserver.sendmail(from_email, to_email, msg.as_string()) mailserver.quit() ``` Ensure that the SMTP server is accessible and not blocked by any network restrictions. 5. **Check Worker Access to Reports**: Verify that the worker can access the report URL specified by `WEBDRIVER_BASEURL`. Ensure the URL is correct and that the worker can authenticate if necessary <sup>[[2]](https://github.com/apache/superset/blob/master/docs/docs/configuration/alerts-reports.mdx)</sup>. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* -- This is an automated message from the Apache Git Service.
