Can't set Zwave parameters anymore

I dont know if this should be in Zwave forum or here. I set Z wave parameters via a MQTT node. Now they dont work anymore. Heres the flow that used to work. And here’s the error I get when I open of MQTT Explorer.

Apparently because I was late to the update, they changed how you have to command it. Heres what works now.

msg.payload = {     
    "args": [
        { "commandClass": 112, "nodeId": 67 },
        "set",
        [{ parameter: 16, value: 50268713, valueSize: 4 }]
    ]
    }
return msg;
