Normalizr is not processing data in envelope

Question

I am using normalizr for data that I receive from Api. When I am receiving list I get normalized entities as expected.

But when I send request that updates one entity, I am receiving only one entity wrapped in data envelope witch is not processed by normalizr correctly.

// Normalize setting
import { Schema, arrayOf } from 'normalizr'

export const player = new Schema('players')
export const arrayOfPlayers = arrayOf(player)

//This is what I use for normalize 
response => normalize(response, {players: schema.player})

And I am receiving data like following with only one player in the list:

{
    code: 200,
    message: '',
    data: { 
        players: [{
            id: 20
            username: 'Gamer'
        }]
    }
}

What I should change to retrieve player as normalized entity?

update:

Example of Api call.

  fetch(
    url,
    { credentials: 'include' }
  )
    .then(checkStatus)
    .then(response => response.json())
    .then(response => normalize(response, {players: schema.player})) 
    .then( // dispatch redux action )
    .catch(function (error) {
    })

Answer 1

if you receive array you should use arrayOf ,otherwise refer to object through res.data.players[0]

change this

normalize(response, {players: schema.player} ) 

to:

1)

normalize(response.data, {players: arrayOf(schema.player) })

result will be

{
    entities: {
        players: {
            20: {
                id: 20,
                username: "Gamer"
            }
        }
    },
    result: {
        players: [
            20
        ]
    }
}

2)

normalize(res.data.players[0], player)

result will be

{
    entities: {
        players: {
            20: {
                id: 20,
                username: "Gamer"
            }
        }
    },
    result: 20
}
