Having this error after moving to webpack2.

Entire log:

    var identifier = identifierPrefix + module.identifier();
                                              ^

This is the plugin's config:

// ...
new HardSourcePlugin({
   cacheDirectory: `${dirname}.cache/[confighash]`,
   recordsPath: `${dirname}.cache/[confighash]/records.json`,
   configHash: function configHash(webpackConfig) {
       return require('node-object-hash')().hash(webpackConfig);
   },
   environmentHash: {
       root: `${process.cwd()}/`,
       directories: ['node_modules'],
       files: ['package.json']
   }
}),
// ...

Will appreciate any help!

@legomushroom I was looking at this earlier to start mulling over what is going on. This is frankly super weird. This error implies that the function erroring is getting no values when its called. No error or module. If the wrapped factory found no module, I think it is supposed to give an error which the function will forward.

Is there any more of your config you can share?

Hi @mzgoddard!

Thanks for the response.
I figured out the exact problem. I was using webpack.IgnorePlugin (for moment.js issue) like this:

new webpack.IgnorePlugin(/^\.\/locale$/, /moment$/)

This caused the error. Yep, both error and module were undefined. Works like a charm after removing the IgnorePlugin.

Awesome. Thanks for letting me know that'll really help me add units and support for Ignore.
