Receiving an error on initial script run: yarn start

yarn run v1.9.4
$ node tools/server.js
C:\GitHub\react-horizontal-timeline\node_modules\webpack\lib\webpack.js:31
throw new WebpackOptionsValidationError(webpackOptionsValidationErrors);
^

WebpackOptionsValidationError: Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.

Symptom:
File: webpack.js
Line: 14
Code:
const webpackOptionsSchema = require("../schemas/WebpackOptions.json");

No directory exists at ../schemas/ in the current repository (sibling to src). Please add this missing json file.

Steps taken:

1. git clone project
2. yarn install
3. yarn start

I'm not sure why there are missing artifacts, but I'm running in a fresh VM so perhaps there's something global that's missing from the package.json. Not having any issues with 6 other projects I've evaluated today or the roughly 20 this week.

Follow below steps:

Running the development version

• Just clone the repo and do an npm install (or yarn install)
• Note: You will need to do npm install react react-dom to install peerDependencies as both yarn and npm don't do this.
• Run npm run start/npm start/yarn start.
• Then go to localhost:5001/demos/<demo_name>/index.html to see the fruits of your labor.
