Hello everyone,
I'm using supertoken in react js but when try to signup with below fileds : 
{
  "formFields": [
    {
      "id": "email",
      "value": "learner1@yopmail.com"
    },
    {
      "id": "password",
      "value": "Admin@123"
    },
    {
      "id": "firstName",
      "value": "Learner"
    },
    {
      "id": "lastName",
      "value": "Test"
    },
    {
      "id": "phoneNumber",
      "value": "123456789"
    },
    {
      "id": "postCode",
      "value": "388140"
    },
    {
      "id": "dob",
      "value": "01/01/1993"
    },
    {
      "id": "gender",
      "value": "male"
    }
  ]
}

But getting thie message from supertoken site : "Are you sending too many / too few formFields?"
