Error in HotModuleReplacementPlugin after upgrading from 2 to 3.

** What is the current behavior?**
Upgrading from webpack 2 to 3, runningwebpack in the commandline, gives me an error in HotModuleReplacementPlugin.Removing the plugin makes webpack pass.

C:\Users\Documents\project\node_modules\webpack\lib\HotModuleReplacementPlugin.js:59
                                        records.chunkModuleIds[chunk.id] = chunk.mapModules(m => m.id);
