What happended?

So I've written a plugin for integrating printful APIs into product creation (and more), it's available on npm https://npmjs.com/package/@vymalo/medusa-printful.

The plugin, while in development phases work fine (APIs are callable, modules are loaded, subscribers are loaded,...) when compiled, it fails directly to load everything.

Expected behavior

The content of my plugin should be loaded, simply. I could then have access to my created endpoints.

Actual behavior

I get the error:

Unable to find the plugin "@vymalo/medusa-printful".

Then I located the file resolve-plugin.ts and still couldn't make it to work, after two days in total of editing.
