I am not sure of the solution here, as it seems to stem from a dependency that hasn't been touched in years: https://github.com/http-party/node-portfinder

ISSUES:

• Update "async" dependency http-party/node-portfinder#126
• node-portfinder not supported anymore webpack/webpack-dev-server#4383

I'm creating this issue mostly as a reference, as I don't think this repo can do anything reasonable to resolve this situations. If the maintainers want to close this, go for it, at least people will find it through google.

This repo indeed cannot do anything about it. It needs to be solved in portfinder or in webpack-dev-server (by replacing portfinder)
