Object prototype may only be an Object or null: undefined

[cosmin-novac]

The moment I require the package with
const Epub = require("epub-gen");
I receive the following error message:

Uncaught (in promise) TypeError: Object prototype may only be an Object or null: undefined

If I then try to call new Epub(...), I receive:

Uncaught (in promise) TypeError: Epub is not a constructor
