Answer 1

The solution to this is two swap the order of 2 of the plugins

from:

plugins: [
    resolve(),
    commonjs(),
    babel({ 
        exclude: 'node_modules/**',
        presets: ['@babel/env', '@babel/preset-react']
    })
],

to:

plugins: [
    resolve(),
    babel({ 
        exclude: 'node_modules/**',
        presets: ['@babel/env', '@babel/preset-react']
    }),
    commonjs()
],
