webpack-bundle v15+ throws Error: Cannot find module 'mini-css-extract-plugin/dist/CssDependency'

[wyllys66]

Summary

When using the latest @next/webpack-bundle (^15.2) with next 15.1.6, when I start my service in dev mode, it throws lots of warnings. If I downgrade webpack-bundle to 14.2, it works fine.
Example of errors:
