Normalizing my nested JSON with normalizr

I'm having the following JSON from my service:

[  
   {  
      "name":"Voter1",
      "id":1,
      "votingCard":{  
         "verificationCodes":[  
            "3I08jA",
            "3x0eyE",
            "2_i69I"
         ],
         "votingCode":"7zCOelDnjfBm7TtFydc4QodgonG",
         "finalizationCode":"jyYu",
         "confirmationCode":"4ACfcpBVH45iAXqg7hJ0tbEe_tV"
      }    
   },
    .....
   {  
      "id":5,
      "name":"Voter5",
      "votingCard":{  
         "verificationCodes":[  
            "2c9I9a",
            "3bEeEa",
            "1gPKx2"
         ],
         "confirmationCode":"4Z7wNG35VR2UMO6-W-0aZVEhbLM",
         "votingCode":"6YQ2x-c8LXJZF05gh3zTajU79ct",
         "finalizationCode":"S0CY"
      }
   }
]

And would like to get it normalized, so a list of votingCards and a list of voters with a "votingCard" property referencing the votingCard by id.

import { normalize, schema } from 'normalizr';

const votingCard = new schema.Entity('votingCard');

const voter = new schema.Entity('voter', {
    votingCard: votingCard,
});

const votersSchema = new schema.Array(voter);


const mutations = {
    SOCKET_SYNCVOTERS: (state, data) => {
        var input = JSON.parse(data);
        const normalizedData = normalize(input, votersSchema);
        console.log(normalizedData);
    },
};

However, I'm not getting what I want:

Why is there an "undefined"?

I think you need to specify an ‘idAttribute’ in the options for the votingCard entity - the problem is that normalizr can’t find an ‘id’ field in those objects so they are all being picked up as id undefined and overwriting each other in entities. See: https://github.com/paularmstrong/normalizr/blob/master/docs/api.md#schema
