<!-- Answer --> This 404 error is almost always caused by missing or incomplete frontend static assets. In Superset 4.1.x, the frontend build process (webpack) can still be running in the background after `docker compose up` finishes, so the UI may not work until the build is done. Make sure to check your container logs for webpack or asset build completion messages before using the UI. If you still see 404s after waiting, try running `npm install` and `npm run build` manually in the `superset-frontend` directory inside your container, then restart Superset. Also, recent versions serve assets on port 9000 by default, not 8088—so try accessing Superset on port 9000 if you aren't already. More details and troubleshooting steps are in [this issue](https://github.com/apache/superset/issues/33875) and [this one](https://github.com/apache/superset/issues/32324). <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
