Microsoft Forms -> Upload File -> Add to folder in SharePoint

Hi folks,

I'm working with a workflow whereby someone completes a Microsoft Form, including uploading a file, which then creates a task in Planner (fine), emails some notifications (fine), and adds the uploaded file to a specific folder in SharePoint. That's where my issue is. I thought I had it down, but it's not adding the uploaded file to SharePoint, just a useless null doc. Any tips here would be massively helpful.

Notes: I'm not wanting to add the uploaded file to a list in SharePoint per se, but to an existing document repo.
