const stream = got.stream(presignedURL);

Confirmed.

However:

❯ file 1000503577.pdf
1000503577.pdf: data

The file command line tool is usually able to detect valid PDFs.

Actually, you have corrupted the PDF. It starts with unrelated data:

--fa92d6cf-98aa-4886-8eeb-667d510d131a..Content-Disposition: form-data; name=file; filename="test document - doc upload.pdf"; filename*=utf-8''test%20document%20-%20doc%20upload.pdf....
