WebOSTV payload not available

I cant seem to send any payload to webos command . How do i set which volume, or which channel, or which app when using commands that require extra args

{"id": 71, "type": "result", "success": false, "error": {"code": "unknown_error", "message": "extra keys not allowed @ data['payload']"}}	

Also, another question. How do I get the result ?

When i use "com.webos.applicationManager/listLaunchPoints" it just answer with state on or off . This happen with every get command

The first question is no longer valid. An update to 111 solved it. The second question stills eldues me
