TypeError: Cannot read property 'properties' of undefined

google search gives this as a fix...

which calls for an updated package.json.

 "webpack": "^4.20.2",
 "webpack-cli": "^3.1.1",

fixed the problem for me on windows 8, node 10.12

I did encounter this issue and was raising an issue for it but noticed this existing issue.
Maybe just to a pull request on package.json instead with the fixed versions?
