When I am learning Writing your AngularJS with Redux

I got the the error "ERROR in The "path" argument must be of type string. Received type undefined webpack: Failed to compile."

At last I figured out the issue by add filename (filename: 'index.html',) to webpack.config.js accoring to CrzMarvin solution.

I had the same problem before,then I think it's something wrong with the plugin. then, I add filename to this plugin.It worked.

// webpack.config.js

plugins: [
    new HtmlWebpackPlugin({
        title: 'use plugin',
        filename: 'index.html'
    })
]

The problem of the issue is related with Node 6 and above. Changing it for Node 5.x instead will probably fix the issue.
