Hey there, @samarsrivastav! I'm here to help you with your bug, answer questions, and guide you on becoming a contributor. Let's squash those bugs together!

It seems like you're encountering an issue where the Superset frontend is not accessible despite the webpack-dev-server running successfully. Here are some steps and considerations to help troubleshoot this issue:

1. Check Backend Server: Ensure that the Superset backend server is running. The frontend proxies requests to the backend server, which should be running on http://localhost:8088. You can start the backend using Docker Compose as recommended in the Superset documentation.

2. Verify Port Configuration: The webpack-dev-server should be running on http://localhost:9000, and it proxies backend requests to http://localhost:8088. Make sure that these ports are not blocked by any firewall or proxy settings on your machine.

3. Environment Variables: Ensure that your environment variables are correctly set. For local development, you might need to set BUILD_SUPERSET_FRONTEND_IN_DOCKER=false if you are not using Docker for the frontend, and SUPERSET_PORT=8088 for the backend ^[1].

4. Docker Setup: If you are using Docker, ensure that all services are up and running. You can check the status of the services with docker compose ps.

5. Network Configuration: Check your network settings to ensure that there are no proxy or firewall rules blocking access to localhost.

6. Browser Cache: Clear your browser cache or try accessing the application in an incognito window to rule out any caching issues.

If these steps do not resolve the issue, you might want to look into any specific error messages in the browser's developer console or the terminal where the backend is running for more clues.
