I encountered the following issue while executing the above code

this looks like import error - like what happens if browser lib is getting imported server side. i have no idea what your environment is like, but the fact you're using process.env makes me believe its an SSR style setup. in which case, you need to lazy-import library in browser-only as using global import will make SSR try to bake it into bundle and that is never going to work.
