Get HTTP 400 error when invoking upload file API (https://upload.box.com/api/2.0/files/content). The message says “Malformed stream”, but gives no additional information. Tried the exact payload as specified in this box documentation page (https://developer.box.com/guides/uploads/direct/file/) and run it in Postman and still get the same error.
