webpack-dev-server (client) crashes when the backend server restarts on Mac

This issue does does not happen when I developed on ubuntu. On Mac, the error is:

    Entrypoint undefined = ../client/app.html
ℹ ｢wdm｣: Failed to compile.

Someone reported that the issue was not fatal before node 10. I started working on Mac with VSCode almost at the same time I upgrade node, so hard to tell if it's the different with when I was developing on linux.
