Cannot find node module in rails stimulus controller

I have a problem with importing an npm package that I have created into my rails application.

I'm unsure if the problem is in the way I have created the node package or with the rails app.

The package is very simple -> https://www.npmjs.com/package/test-release-stuff

Now when I'm trying to import it into rails (I install it vie yarn and then see it's in the node modules) and I try to import it into my stimulus controller it tells me that it can't find the module. The error literally says:

Error: Cannot find module 'test-release'stuff'

How I'm importing the module?

I'm doing import foo from 'test-release-stuff'

One thing to note is that when I tried that in a simple react todo app it was imported without any issues.

I have a feeling that it might be something with the webpacker config in my rails app (below is the config) or that it might be something with the node packaga packgage.json file, there might be something incorrect there.

const { webpackConfig, merge } = require('@rails/webpacker');
const { BundleAnalyzerPlugin } = require('webpack-bundle-analyzer');
const plugins = [];

if (process.env.ANALYZE === 'true') {
  plugins.push(new BundleAnalyzerPlugin());
}

const customConfig = {
  resolve: {
    extensions: ['.css'],
  },
  plugins: plugins,
};

module.exports = merge(webpackConfig, customConfig);

then in the production/development/test files I have something like this:

process.env.NODE_ENV = process.env.NODE_ENV || 'production';

const webpackConfig = require('./base');

module.exports = webpackConfig;

It's a rails 6 project.
