client.write - Content should be buffer or file descriptor

[mmumshad]

When I try to write a file with contents as given in example, it comes back with error:

C:\  .... node_modules\scp2\lib\client.js:228
        throw new Error('Content should be buffer or file descriptor');

My code

createFileOnScriptEnginer = function(contents,destinationPath){
  var Client = require('scp2').Client;
  var cl = new Client({
    port: 22,
    host: "10.xxx.xxx.131",
    username: "root",
    privateKey: require('fs').readFileSync("server/components/ssh/ssh_key"),
  });
  cl.write({
    destination: destinationPath,
    content: contents
  }, function(err){

  })
};

createFileOnScriptEnginer('sdfdddddddddsfd','/tmp/testfile.txt');

And the I tried to create Buffer like below. And this time it creates the file but program hangs.

exports.createFileOnScriptEnginer = function(contents,destinationPath){
  var Client = require('scp2').Client;
  var buffer = new Buffer(contents, "utf-8")
  var cl = new Client({
    port: 22,
    host: "10.xxx.xxx.131",
    username: "root",
    privateKey: require('fs').readFileSync("server/components/ssh/ssh_key"),
  });
  cl.write({
    destination: destinationPath,
    content: buffer
  }, function(err){

  })
};
