I am getting an error with atttempting the following PUT request with nodejs.

var request = require('request');
request('http://1xx.xxx.xxx.xxx:8080/maintable/http%3A%2F%2Ftesturl.com
  %2F', 
method: 'PUT', 
json:{"Row":[{"key":"aHR0cHM6Ly9tYWt6ZW9uLndvcmRwcmVzcy5jb20v", "Cell": 
 [{"column":"YmxvZ3NfZGF0YTp1cmw=", "$":    
 "aHR0cHM6Ly9tYWt6ZW9uLndvcmRwcmVzcy5jb20v"},
 {"column":"YmxvZ3NfZGF0YTppbnNlcnREYXRl", "$": "MTQ5Njg3ODk1OA=="},    
 {"column":"YmxvZ3NfZGF0YTpzdGF0dXM=", "$": "QWN0aXZl"}], 
}]}, 
function (error, response, body) {
    console.log('error:', error);
    console.log('statusCode:', response && response.statusCode);
    console.log('body:', body);
}
);
