How to update composition BDM with Groovy Script?

Hello,

I created composition BDM and add all contracts using by the groovy script

Once I return the BDM I need to update all contract, so, I added update groovy script, however, I got the error,

Please help me what is the error to indicate.

Thanks in advance

This is the addall operation groovy script

def testTimerList = []
//For each item collected in multiple input
boolean status = false;

timerObjInput.each{
//Add a new composed testTimer instance
testTimerList.add({ currenttestTimerInput ->
def testTimerVar = new com.company.model.TestTimer()
testTimerVar.recommandation = currenttestTimerInput.recommandation
testTimerVar.statusRec = currenttestTimerInput.statusRec;
testTimerVar.timerTask = {
def timerTaskList = []
//For each item collected in multiple input
currenttestTimerInput.timerTask.each{
//Add a new composed timerTask instance
timerTaskList.add({ currenttimerTaskInput ->
def timerTaskVar = new com.company.model.TimerTask()
timerTaskVar.title = currenttimerTaskInput.title
//timerTaskVar.setStartdate((new Date()).format('yyyy.MMMMM.dd hh:mm aaa'));
timerTaskVar.statusTask = currenttimerTaskInput.statusTask
timerTaskVar.startdate = currenttimerTaskInput.startdate
timerTaskVar.enddate = currenttimerTaskInput.enddate
return timerTaskVar
}(it))
}
return timerTaskList}()
return testTimerVar
}(it))
}
return testTimerList

And the this is update script .

recommandObjInput.each{
testTimerList.add({ currenttestTimerInput ->
//def testTimerVar = new TestTimer()
def TestTimer testTimerVar = testTimerList.find{
it.persistenceId == currenttestTimerInput.persistenceId.toLong()
}
testTimerVar.recommandation = currenttestTimerInput.recommandation
testTimerVar.statusRec = currenttestTimerInput.statusRec;

testTimerVar.timerTask = {
def timerTaskList = []
//For each item collected in multiple input
currenttestTimerInput.timerTask.each{
//Add a new composed timerTask instance
timerTaskList.add({ currenttimerTaskInput ->
def timerTaskVar = new com.company.model.TimerTask()
timerTaskVar.title = currenttimerTaskInput.title
//timerTaskVar.setStartdate((new Date()).format('yyyy.MMMMM.dd hh:mm aaa'));
timerTaskVar.statusTask = currenttimerTaskInput.statusTask
timerTaskVar.startdate = currenttimerTaskInput.startdate
timerTaskVar.enddate = currenttimerTaskInput.enddate
return timerTaskVar
}(it))
}
return timerTaskList}()
return testTimerVar
}(it))
}
return testTimerList

And the error is
