customer query without parameters is not working with just an Auth Header

[protob]

Describe the bug
The customer query with just an Auth Header is not working without parameters

To Reproduce

1. Fire the customer query with valid Authorization header (Bearer TokenString)

query {
  customer {
    id
    customerId
    orderCount
    totalSpent
    orders {
      nodes {
        id
      }
    }
    username
    email
  }
}

2. It returns new_customer data

{
  "data": {
    "customer": {
      "id": "new_customer",
      "customerId": null,
      "isVatExempt": false,
      "hasCalculatedShipping": false,
      "calculatedShipping": false,
      "orderCount": 0,
      "totalSpent": 0,
      "orders": {
        "nodes": []
      },
      "username": null,
      "email": null
    }
  }
}

Expected behavior
It should return the data of the user associated with the provided JWT token.
