Nodejs-Sia API /consensus/validate/transactionset structure

Hi Sia Community

I am playing with the Nodejs-Sia API. However, I am getting stuck trying to call "/consensus/validate/transactionset" through this Node API. The following code is my best attempt at calling it but I get a 'UnhandledPromiseRejectionWarning':

siad.call({url: '/consensus/validate/transactionset',
           body: ("transaction id"),
         }).then((consensus) => {
          console.log(JSON.stringify(consensus))
        })}

Thanks for any help you can provide.
