we want to display a grid report with task ID as task link and business data associated with each task.but we are able to get task id separately using queryprocessanalytics ,

@suganyasrip Few questions here:
1. What is the category(such as Processes Per Process Model, Tasks Per Process Model, Tasks Per User etc.) of the Report?
2. What is "MyModel"? Have you mentioned it intentionally to hide implementation details from us or are you providing the process model object to contextProcessModels argument in the similar fashion?

Also please check for the presence of the errorMessage in the result(mentioned above by you) and it might be at last in the datasubset.
