How to read http json response from service


i'm trying to read http json response from service. The response size  res.HttpResponse.Data.Size =  19610854 

ClassMethod getData(pCode,pDate, pGlb) As %Status

    Do res.Get("TestService/getData?dateTo="_$ZDate(pDate,3))
    Set stat=res.HttpResponse.StatusCode
    Do res.HttpResponse.Data.Rewind() 
    Set httpResponse=res.HttpResponse.Data.Read(res.HttpResponse.Data.Size,.sc)
    Set dynObj = [].%FromJSON(httpResponse)
    Set iter = dynObj.Stmt.%GetIterator()
    While iter.%GetNext(.key, .value){
        Set @pGlb@(item)=$ListBuild(SomeField1,SomeField1)


when trying to get data from global :

Set result=##class(test.Data).getData("PM",pDate,$Name(^||Data))
w ^||owData -  Error <UNDEFINED>

I thing the problem in that the size of httpResponse is too big/

how I can read such http response ?
