Issues with har-validator package

[kaytrance]

Hi

While following readme instructions and installing packages with npm install I have stumbled into following error

npm ERR! code E404
npm ERR! 404 Not Found - GET https://registry.npmjs.org/har-validator/-/har-validator-5.1.2.tgz
npm ERR! 404

You can remove package-lock.json and again run npm install

I am using node 10.16 with this "gulp": "^3.9.1" version. You can try also use 11.15
