Deserialization issue using "JSONAPI-Serializer"

For following code:-

  var str = JSON.parse(new Buffer(req.body.profile, 'base64').toString());
   var UserDeserialize = new JSONAPIDeserializer();
   var obj = UserDeserialize.deserialize(str).then(result => {
    console.log(result);

If i am using entering user input like:-

**

**

Where profile=eyAiZGF0YSI6IFsgeyAidHlwZSI6ICJpZHMiLCAiaWQiOiJ0ZXN0IiB9IF0gfQ== is

{ "data": [ { "type": "ids", "id":"test" } ] }`

But if I am trying to pass serialized function like this way:-

{ "data": [ { "type": "ids", "id":function(){eval('console.log(Hello World)')} } ] }

This is showing error to me

syntaxError: Unexpected token u in JSON at position 35<br> &nbsp; &nbsp;at JSON.parse (&lt;anonymous&gt;)<br> &nbsp; &nbsp;at /Users/acid/node_js/localhost/velekaam/hacked.js:16:19<br> &nbsp; &nbsp;at Layer.handle [as handle_request] (/Users/acid/node_js/node_modules/express/lib/router/layer.js:95:5)<br> &nbsp; &nbsp;at next (/Users/acid/node_js/node_modules/express/lib/router/route.js:137:13)<br> &nbsp; &nbsp;at Route.dispatch (/Users/acid/node_js/node_modules/express/lib/router/route.js:112:3)<br> &nbsp; &nbsp;at Layer.handle [as handle_request]

Can anyone please tell me how I pass

{ "data": [ { "type": "ids", "id":function(){eval('console.log(Hello World)')} } ] } so that I am able to pass this through de-serializer function and get result as "Hello Word". ?
