Hey @darshan200! I'm a bot here to help you with bug fixes, questions, and contributions. Let's tackle this report generation issue together.

I found some relevant discussions and issues that might help address the report generation issue with the dashboard option in Superset:

1. There is an open discussion titled Alerts & Reporting - Selenium timed out / DNS Resolution that might be related to your issue. It suggests checking the configuration settings for synchronous and asynchronous screenshot generation. Ensure that the feature flags ENABLE_DASHBOARD_SCREENSHOT_ENDPOINTS and ENABLE_DASHBOARD_DOWNLOAD_WEBDRIVER_SCREENSHOT are set to False to use the synchronous version. If the logs still indicate asynchronous triggering, double-check the configuration settings ^[1].

2. Another discussion, Alerts and reports notification fails due to selenium exception, might provide insights into similar issues with Selenium exceptions ^[2].

Additionally, ensure that your Selenium and WebDriver configurations are correctly set up in your superset_config.py or superset_config_docker.py file. Key settings include WEBDRIVER_TYPE, WEBDRIVER_WINDOW, and WEBDRIVER_BASEURL. These configurations are crucial for proper screenshot generation ^[3][4].

If the issue persists, reviewing the specific error messages or logs generated during the failure can provide more context. Common errors include SMTP connection issues or uncaught exceptions ^[5].
