Play ScalaJSON Reads[T] parsing ValidationError(error.path.missing,WrappedArray())

Question

i have a funny json data looking as:

[ {
  \"internal_network\" : [ {
    \"address\" : [ {
      \"address_id\" : 2,
      \"address\" : \"172.16.20.1/24\"
         


        

Answer 1

The error is telling you that instead of /switch_id it got an array. So it seems like you should read the JSON as a List[Switch] instead of just Switch

Assuming your Reads (didn't test them) are correct this should work:

val json: JsValue = Json.parse(jsonChunk)
println(json.validate[List[TheSwitch]])
