hello im building the sign in request and im sending this as a body

{
  "formFields": [
    {
      "id": "firstName",
      "value": "d"
    },
    {
      "id": "lastName",
      "value": "d"
    },
    {
      "id": "email",
      "value": "dddddddd"
    },
    {
      "id": "phone",
      "value": "ddddddddd"
    },
    {
      "id": "password",
      "value": "pass1234"
    },
    {
      "id": "address",
      "value": ""
    }
  ]
}

and im getting this as an answer ``{"message":"Missing input param: formFields"}`` im trying to copy the exact same request as in postman that already works
