Template cannot be applied as TemplateArgument: HarmonyImportDependency

I can’t understand what it means. It’s a bug? Maybe, I doing something wrong?

error stack:

vendor.js

The template for the DedupePlugin is missing for harmony imports. As workaround disable the DedupePlugin.

You can’t use the DedupePlugin with wbepack2 and Angular 2 until https://github.com/webpack/webpack/issues/2644 is solved.
