SharePoint Workflow 2013 always Suspended showing Looking up a value using a key is not supported

[SakthiRam D]

I am having this issue in SP Workflow 2013 that every time it executed , it always goes to Suspended stage.

However, After completing the web service call and reading the d/results it shows the error

RequestorId: 3d5f4981-27fc-e36f-0000-000000000000. Details: An unhandled exception occurred during the execution of the workflow instance. Exception details: System.InvalidOperationException: Looking up a value using a key is not supported on an instance of 'Microsoft.Activities.Dynamic.DynamicPrimitive'. at Microsoft.Activities.Dynamic.DynamicItem.TryGetValue(String key, DynamicItem& value) at Microsoft.Activities.Dynamic.DynamicValueBuilder.PathSegmentFactory.ObjectPathSegment.Get(DynamicItem obj) at Microsoft.Activities.GetDynamicValueProperty1.Execute(CodeActivityContext context) at System.Activities.CodeActivity1.InternalExecute(ActivityInstance instance, ActivityExecutor executor, BookmarkManager bookmarkManager) at System.Activities.Runtime.ActivityExecutor.ExecuteActivityWorkItem.ExecuteBody(ActivityExecutor executor, BookmarkManager bookmarkManager, Location resultLocation)

Kindly assist

Cheers, Thank you!
