Kodi JSON command in Domoticz not working anymore

[jberinga]

With Domoticz on my Synology NAS I now have this command within a blocky to play a playlist:

192.168.178.111:8080/jsonrpc?request={"jsonrpc":"2.0","method":"Player.Open","id":1,"params":{"item":{"file":"special://profile/playlists/music/Months.xsp"}}}

But with Kodi updated on my Shield to V18 Leia this isn't working anymore, because the way the JSON api works in Kodi has been changed (https://forum.kodi.tv/showthread.php?tid=324598) and I have no idea how I can get the command in Domoticz working again.

Is there anyone who can help me with this?

Thanks!
