[Bug] aria2.addTorrent can't handle options, resulting: "Bad Request"

[jc3213]

I'm using json-rpc with javascript, I can download torrent with the json request below

{"id":"","jsonrpc":"2.0","method":"aria2.addTorrent","params":["token:mytoken","B64TORRENT"]}

But it will report Bad Request if I use any options to aria2 json-rpc.

{"id":"","jsonrpc":"2.0","method":"aria2.addTorrent","params":["token:mytoken","B64TORRENT",{"dir":"D:/mydir"}]}

The error persists even if I use empty options as {}

{"id":"","jsonrpc":"2.0","method":"aria2.addTorrent","params":["token:mytoken","B64TORRENT",{}]}

It works fine for aria2.addMetalink when downloading metalink files.
