To fix the problem just use.

JSON.stringify(res.data)

data is not JSON.

It is an object which is being implicitly converted to a string:

var data = { for: "example" };
var what_you_are_sending = "" + data;
console.log(what_you_are_sending);

The server is trying to parse it as JSON. The [ is the start of an array. The o is an error. Then it stops.

You need to convert the object to JSON with JSON.stringify.

var data = JSON.stringify({ for: "example" });
var what_you_should_send = "" + data;
console.log(what_you_should_send);
