Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch bark-js@1.2.0 for the project I'm working on.

Here is the diff that solved my above problem:

First off, thanks for the thorough report!

This seems related to #13 and #23 which are partially fixed by #24 (which is basically the same as the diff you posted). I would love to know more about your build process to understand what may be causing the issue - are you using Rollup, Webpack, Esbuild or similar? Could you share you build config here?

Regardless, since it seems to be a recurring problem I will merge and publish a patch this weekend.
