Color Contrast Example - Build Error #524
Description
What is wrong?
npm run build fails with slightly modified color contrast example
Where does it happen?
It happens when trying to run npm run build on my Mac running NodeJS LTS.
How do we replicate the issue?
Build script in package.json: "build": "cross-env BABEL_ENV=production babel src --out-dir lib",
src/index.js -> lib/index.js
TypeError: src/neuralNetTest.js: Cannot read property 'contexts' of null
As you can see, I have an index.js that is able to build, but the example code contained in src/neuralNetTest.js shows a TypeError.
How important is this (1-5)?
4-5
Expected behavior (i.e. solution)
Build without errors
