Failed to parse source map for this package

[spacether]

Your package includes source maps like so which include references to src folders:
https://www.npmjs.com/package/@bradgarropy/use-countdown?activeTab=code
But you do not distribute that src folder in your distribution

So npm start and npm run build throw warnings about your package like:
