json to case classes extraction giving error - json

Question

I have a json from which i have to populate the value to the scala case classes but it's giving error while I'm populating it.
I'm using lift json 3.3.0 for converting
Scala Case Classes
package sampling
case class JobJson(name:String,id:String,dataflowId:String,properties:Properties)
case class Properties(activities:List[Activity],activityGroup:List[ActivityGroup])
case class Activity(name:String,types:String,id:String,inputs:List[Inputs],outputs:List[Outputs],runtimeInfo:Map[String,Any],start:String,end:String)
case class Inputs(properties:InputProperties,sourceConnection:SourceConnection)
case class InputProperties(structure:List[Structure],translator:List[Translator])
case class Structure(index:Int,name:String,dataType:String)
case class Translator(index:Int,name:String,dataType:String)
case class SourceConnection(connectionType:String,fileName:String,linkedService:String,location:String,datasetId:String,datafileId:String)
case class Outputs(properties:OutputProperties,destConnection:DestConnection)
case class OutputProperties(structure:List[OutputStructure],translator:String)
case class OutputStructure(index:Int,name:String,dataType:String)
case class DestConnection(connectionType:String,fileName:String,linkedService:String,location:String,datasetId:String,datafileId:String)
case class ActivityGroup(name:String,id:String,properties:ActivityGroupProperty)
case class ActivityGroupProperty(activityList:List[ActivityList])
case class ActivityList(id:String,order:String)
Code Where getting populated
implicit val formats = net.liftweb.json.DefaultFormats;
val p= parse(json).extract[JobJson];
println(p);
