My webpack.config.js:

/* global process */
var path = require("path");
var webpack = require("webpack");

var globalTag = new webpack.DefinePlugin({
  __DEV__: JSON.stringify(JSON.parse(process.env.BUILD_DEV || 'true')),
  __PRERELEASE__: JSON.stringify(JSON.parse(process.env.BUILD_PRERELEASE || 'false'))
});

var config = {
    cache: true,
    entry: [
        'webpack/hot/dev-server',
        './client.js'],
    output: {
        path: process.env.NODE_ENV === 'production' ? './dist/assets' : './build/assets',
        publicPath: "public/assets/",
        filename: "[name].js",
        chunkFilename: "[chunkhash].js"
    },
    devServer: {
        info: false, //  --no-info option
        hot: true,
        colors: true,
        proxy: {
            "*": 'http://iam.dev:4000'
        }
    },
    module: {
        loaders: [
              //.......
        ]
    },
    resolve: {
        extensions: ['', '.js', '.jsx', '.css', '.styl', '.coffee'],
        root: [path.join(__dirname, "bower_components")]
    },
    plugins: [
        globalTag,
        new webpack.ResolverPlugin(
            new webpack.ResolverPlugin.DirectoryDescriptionFilePlugin("bower.json", ["main"])
        ),
        new webpack.optimize.DedupePlugin(),
        new webpack.optimize.OccurenceOrderPlugin(),
        new webpack.optimize.UglifyJsPlugin()]
};

module.exports = config;

and below command line options works for me:

webpack-dev-server --devtool eval --colors --hot --content-base-target 'http://mihawk.dev:4000'

I checked OriginalSource.js#61, and seem like options was undefined.
I try to fix it at lenage/webpack-core@7601bec , but it's turns out all my css not required.

any idea?

I am also seeing this. Though I'm seeing it with webpack in general. So I'm guessing it's a webpack-core issue.

My solution for now is to simply downgrade to the latest 1.7.x release :-( Let me know if there's any info I can provide to figure out what the issue is.

I fixed the errors in this issue by upgrading less and less-loader dependencies, but my styles were still not being loaded. I ended up actually resolving the problem (that my styles were not being included correctly) by then bumping my extract-text-webpack-plugin dependency.

Here's a snippet of my current (working) versions for the loaders and plugins that were involved with this issue for my project:

    "babel-loader": "5.1.4",
    "extract-text-webpack-plugin": "0.8.1",
    "less": "2.5.1",
    "less-loader": "2.2.0",

Closing issue because it was either webpack(not dev-server), or less. If anyone still has this issue, feel free to comment and I'll re-open.

I am facing the same issue, Cannot read property originalSource of undefined.
I don't have any property called originalSource. I am trying to use GridLayout
