How to Upload a PDF as a Stream Instead of a Buffer in Noloco API via Make.com?

I’m using Noloco and want to upload a PDF file via the API module in Make.com. The “Update Record” module doesn’t allow file uploads, so I’m using the API call instead. However, when I use the HTTP Get a File module, it outputs a buffer. Noloco requires the file to be uploaded as a stream. How can I convert or output the data as a stream instead of a buffer?
