null values on subscriptions except ID

[AlbertoSinigaglia]

HI,
I'm having an issue with subscriptions, since I get the event from Amplify.subscribe, but all the fields, except the ID are null

To Reproduce On the Application

Amplify.addPlugin(AWSCognitoAuthPlugin())
Amplify.addPlugin(AWSApiPlugin())
Amplify.configure(applicationContext)

Log in with Cognito

Amplify.API.subscribe(
    ModelSubscription.onCreate(Player::class.java),
    { Log.i("ApiQuickStart", "Subscription established") },
    { onCreated ->
        Log.i("TESTTTT", onCreated.toString())
        if(onCreated.data.name.equals(Amplify.Auth.currentUser.username, ignoreCase = true)){
            onCreated.data.gameroom.id
            Log.i("io", onCreated.data.toString())
            sub!!.cancel()
        }
        Log.i("ApiQuickStart", "Todo create subscription received: " + onCreated.data) },
    { onFailure -> Log.e("ApiQuickStart", "Subscription failed", onFailure) },
    { Log.i("ApiQuickStart", "Subscription completed") }
)

In the console i can see:

Subscription established

And then

I/TESTTTT: GraphQLResponse{data='Player {id=77c44e03-999b-465d-bb51-293cf8dd8767, lastinteraction=null, name=null, score=null, gameroom=null}', errors='[]'}

I think this is a problem with permission possibly?
My schema looks like this on AppSync Console:

input CreateGameRoomInput {
    id: ID
}

input CreatePlayerInput {
    lastinteraction: AWSTimestamp
    name: String!
    score: Int

        limit: Int,
        nextToken: String
    ): ModelPlayerConnection

    updatedAt: AWSDateTime!
}

    not: ModelPlayerConditionInput
}

type ModelPlayerConnection @aws_iam
@aws_cognito_user_pools {

input ModelPlayerFilterInput {
    lastinteraction: ModelIntInput
    name: ModelStringInput
    score: ModelIntInput
    id: ModelIDInput
    gameid: ModelIDInput
    and: [ModelPlayerFilterInput]
    or: [ModelPlayerFilterInput]
    not: ModelPlayerFilterInput

input ModelSizeInput {

    attributeType: ModelAttributeTypes
    size: ModelSizeInput
}

type Mutation @aws_iam
@aws_cognito_user_pools {
    createGameRoom(input: CreateGameRoomInput!, condition: ModelGameRoomConditionInput): GameRoom
    updateGameRoom(input: UpdateGameRoomInput!, condition: ModelGameRoomConditionInput): GameRoom
    deleteGameRoom(input: DeleteGameRoomInput!, condition: ModelGameRoomConditionInput): GameRoom
    createPlayer(input: CreatePlayerInput!, condition: ModelPlayerConditionInput): Player
    updatePlayer(input: UpdatePlayerInput!, condition: ModelPlayerConditionInput): Player
    deletePlayer(input: DeletePlayerInput!, condition: ModelPlayerConditionInput): Player
}

type Player @aws_iam
@aws_cognito_user_pools {
    lastinteraction: AWSTimestamp
    name: String
    score: Int
    id: ID!
    gameid: ID!
    gameroom: GameRoom
    createdAt: AWSDateTime!
    updatedAt: AWSDateTime!
}

type Query @aws_iam
@aws_cognito_user_pools {
    getGameRoom(id: ID!): GameRoom
    listGameRooms(filter: ModelGameRoomFilterInput, limit: Int, nextToken: String): ModelGameRoomConnection
    getPlayer(id: ID!): Player
    listPlayers(filter: ModelPlayerFilterInput, limit: Int, nextToken: String): ModelPlayerConnection
}

type Subscription @aws_iam
@aws_cognito_user_pools {
    onCreateGameRoom: GameRoom
        @aws_subscribe(mutations: ["createGameRoom"])
    onUpdateGameRoom: GameRoom
        @aws_subscribe(mutations: ["updateGameRoom"])
    onDeleteGameRoom: GameRoom
        @aws_subscribe(mutations: ["deleteGameRoom"])
    onCreatePlayer: Player
        @aws_subscribe(mutations: ["createPlayer"])
    onUpdatePlayer: Player
        @aws_subscribe(mutations: ["updatePlayer"])
    onDeletePlayer: Player
        @aws_subscribe(mutations: ["deletePlayer"])
}

input UpdateGameRoomInput {
    id: ID!
}

input UpdatePlayerInput {
    lastinteraction: AWSTimestamp
    name: String
    score: Int
    id: ID!
    gameid: ID
}

So it's supposed to be authorized to see those fileds...

Or, since the authorization like @aws_cognito_user_pools manually from the AppSync console, and so locally Amplify "don't have this update" and maybe is not sending the Cognito Token?

UPDATE With the "update" subscription, I'm getting all the fields...
