There seems to be an issue with newer strapi versions, where the current method of importing packages within the app file seems to have changed or it's not working.

[thunt4jr]

This has been resolved. The issues was inside the ckeditor.txt.

Not sure how this was added but this was causing the issues.

CKEditor5.markdownGfm.Markdown,

[EmilianoTalamo]

I wouldn't call it solved yet because the import of third party plugins for ckeditor (like the one you're mentioning, markdownGfm) is not working.

That plugin is required to output the custom field as markdown. Someone on your project added it because it's also listed as a dependency on your package.json.
