Issue in retrieving api response to dataset

[DeviE (Devi)]

Hi, I am trying to retrieve response from sharepoint list using http request activity. I used dataset to read the XML string value.

But i am getting the below error
System.ArgumentNullException: Value cannot be null.
Parameter name: TargetObject
at System.Activities.Statements.MethodExecutor.BeginExecuteMethod(AsyncCodeActivityContext context, AsyncCallback callback, Object state)

HI @DeviE,

Parameter name: TargetObject

Make sure did you created object for dataset.
DS_Master=new DataSet()
