Parse json array to a case class in scala using playframework with the fields in json not matching the fields in case class

Question

I am trying to parse a simple json array to a case class using scala and play framework. Below is the code

package com.learning.avinash.query

import play.api.libs.json.{JsPath, Json, Reads, Writes, __}
import play.api.libs.functional.syntax._

object ParseJson extends App {

  case class InfoForm(avinash: String, kranti: String, prasanth: String)

  object InfoForm {

    implicit val reads: Reads[InfoForm] = (
      (JsPath \ "username").read[String] ~
        (JsPath \ "id").read[String] ~
        (JsPath \ "full_name").read[String]
      )(InfoForm.apply _)

  }

  val json = """ {
  "data":  [
     {
      "username": "carolinabentocb",
      "id": "363753337",
      "full_name": "Carolina Bento"
    },
     {
      "username": "pereira3044",
      "id": "2141448590",
      "full_name": "Alex"
    }]
}"""

  println(Json.parse(json).as[List[InfoForm]])

}

But i am getting the following exception

Exception in thread "main" play.api.libs.json.JsResultException: JsResultException(errors:List((,List(JsonValidationError(List(error.expected.jsarray),WrappedArray())))))

Finally I could get the result of this. I have done it like this

println((Json.parse(json) \"data" ).as[List[InfoForm]])

This gives me the result

List(InfoForm(carolinabentocb,363753337,Carolina Bento), InfoForm(pereira3044,2141448590,Alex))
