Почему webpack-dev-server не отдаёт бандл для index.hmtl?

<script type="text/javascript" src="bundles/index.js"></script>

const path = require('path');
const webpack = require('webpack');

module.exports = {
    entry: {
        index: './entry_points/index.js'
    },
    output: {
        filename: '[name].js',
        path: path.join(__dirname, '/bundles/')
    },
    watchOptions: {
        pull: true,
        ignored: /node_modules/
    },
    devServer: {
        contentBase: path.join(__dirname),
        historyApiFallback: true,
        port: 9002
    }
};
