I was not sure where to post more code, so I made a minimum project that reveals this, the code is in api.ex where you can also see lots of things commented out from things I tried.
I also attached a har file as exported from the browser when doing the upload, and the body of the request as I see in the logs if I read it via Plug.Conn.read_body(conn), label: "body")

If there are other suggestions on where to post the code to be easier please let me know.
Thank you
