I'm testing with real torrents like this:

http://academictorrents.com/details/b8287ebfa04f879b048d4d4404108cf3e8014352

I get a Bad Request response trying to upload the torrent to the backend. I think the problem is the torrent is too big (2.2MB).

I've been debugging, and the error is thrown here.

                while let Some(chunk) = field.chunk().await.map_err(|_| (ServiceError::BadRequest))? {
                    torrent_cursor.write_all(&chunk)?;
                }

I am still determining the reason. I must first check if the backend is receiving the whole torrent data.
