type mismatch; found : Seq[play.api.libs.json.JsObject] required: Seq[play.api.libs.json.Json.JsValueWrapper] - playframework-2.5

Question

I am working on converting Sequence of Custom Object into JSON format using Play Framework 2.5.6.
Below is my code.
import play.api.libs.json.Json
import play.api.libs.json.JsObject
case class Item (id:Long,name:String,price:Double)
object SerializingListIntoJSON {
def details(itemList: Seq[Item]) = {
**Json.arr(itemList.map(item => Json.obj("id" -> item.id,"name" -> item.name,"price" -> item.price)): _*)**
}
def main(args: Array[String]): Unit = {
val itemList = Seq(Item(1, "Programming Scala", 49.99), Item(2, "Scala in Action", 44.99))
println(details(itemList))
}
}
The code is giving me the compilation error in the bold line saying "type mismatch; found : Seq[play.api.libs.json.JsObject] required: Seq[play.api.libs.json.Json.JsValueWrapper]".
I am not sure what is wrong with my code. Any help on this is deeply appreciated.

The following
def details(itemList: Seq[Item]) = {
JsArray(itemList.map(item =>
Json.obj("id" -> item.id, "name" -> item.name, "price" -> item.price)))
}
produces a result of:
[
{
"id": 1,
"name": "Programming Scala",
"price": 49.99
},
...
]
if that is what you are after? If you haven't seen the Play Scala JSON documentation yet, then you might find discussion of Writes and Reads helpful, amongst other details and examples there.
