This is likely a CORS related issue, see this official page for solutions.
Not sure what impact this will have (if any), but I'm also noting you haven't specified the MIME type and the MIME type of the file is application/octet-stream, consider specifying the correct MIME type for the file i.e. image/jpeg for JPEG.
