Hi i trying to get

htable.dump mytable 
via jsonrpc request

{jsonrpc: "2.0",
method: "htable.dump mytable"}
 {
        "jsonrpc":      "2.0",
        "error":        {
                "code": 500,
                "message":      "Method Not Found"
        }
}

But via kamcmd it wroks perfect

Aslo i see that if i will make request withont param (core.version for example)
IT works fime
