Compilation is always succesful when it should not be

[sandervspl]

For some reason my errors or warnings are not shown, and the compilation is always succesful.
I use webpack-dev-server and webpack-merge to merge two webpack configs.

Edit: Also tried with a project that uses webpack-hot-middleware and webpack-dev-middleware. There it also always compiles succesfully and does not log eslint or build errors.

base:

const baseConfig = {
  mode: 'production',
  output: {
    filename: 'static/js/[name].[hash].js',
    path: paths.resolveRoot('dist'),
    publicPath: '/',
  },

    rules: [
      {
        test: /\.jsx?$/,
        exclude: /node_modules/,
        loader: 'babel-loader',
        options: {
          cacheDirectory: true,
        },
      },
      {
        test: /\.css$/,
        loader: 'style-loader!css-loader',
      },

              limit: 10000,
            },
          },
          {
            loader: '@svgr/webpack',

        ],
      },

  },
  plugins: [
    new webpack.HotModuleReplacementPlugin(),
    new webpack.DefinePlugin(globals),
    new FriendlyErrorsWebpackPlugin({
      compilationSuccessInfo: {

};
