Reproduce the README command with `docker-compose exec web webpack-dev-server`, then compare it with the successful `webpack` command. Start at `node_modules/webpack-dev-server/lib/Server.js` and its `addCompilerHooks` stack frame, checking the project's webpack configuration and reported webpack 3.11.0 setup. Done means the documented dev-server command starts without the TypeError.
