Hey, I tried your plugin in a simple demo and it works well. Now I want to apply it to my team project which is much bigger. Then it failed and throw this error.

Here is the environment:
Node v8.11.3
webpack v4.17.1

Here are part of used plugins:

new webpack.optimize.ModuleConcatenationPlugin(),
new webpack.HashedModuleIdsPlugin(),
new WebpackDeepScopeAnalysisPlugin()

I can't figure out if it is my mistake or a bug of this plugin.
