I have created a list workflow from SPD and assigned a task to the approvers group. The workflow is triggering fine but when i want to fetch some of the columns like WorkflowName is coming with blank. I also verified the Json response from REST API to check values are coming or not? But i found some of the properties are null.
Please some one help me how to fetch these details.
the below is my Json response from the WOrkflow Task list.
