You are not sending a valid JSON response but a String containing the word json therefore the JSON.parse() is failing on the client side. Try this:

app.post('/save', function(req, res) {
  console.log(req.body.objectData);
  res.contentType('json');
  res.send({ some: JSON.stringify({response:'json'}) });
});

JavaScript Object Notation is a way to share data between applications in object format. However, you cannot send an object over an HTTP request without first turning it into a string and sending it as a single variable. The functions JSON.parse() and JSON.stringify() do this for us.
