Facing weird issues on deserialization via JSONAPI-Serializer

If i do like this

var JSONAPIDeserializer = require('jsonapi-serializer').Deserializer;

var UserDeserialize = new JSONAPIDeserializer('id');
UserDeserialize.deserialize({ data: [ { type: 'ids', id: '1' }, { type: 'ids', id: '2' } ] })
.then(a => console.log(a))

I am able to get desired output of deserialization

[ { id: '1' }, { id: '2' } ]

But if i create a variable of serialized data and try to serialize the same like this

var JSONAPIDeserializer = require('jsonapi-serializer').Deserializer;

var test = "{ data: [ { type: 'ids', id: '1' }, { type: 'ids', id: '2' } ] }"
var UserDeserialize = new JSONAPIDeserializer('id');
UserDeserialize.deserialize(test)
.then(a => console.log(a))

I am getting error like this way:-

/Users/acid/node_js/node_modules/jsonapi-serializer/lib/deserializer-utils.js:70
    var dest = keyForAttribute(from.attributes || {});
                                   ^

How I can correct this ?
