REST api - How to find node id associated with a task

sar_pooja

I am retrieving a list of review tasks using REST api - alfresco/service/api/task-instances
In the response I get details of the task instance. How can I get node id associated with the task instance using REST api?

Hi,

You cann't get the the node-id in direct.
In alfresco/service/api/task-instances api you will get

I'm pretty sure that I already associate my item to this workflow. But the workflow package is empty.
Below is my task detail screen.
Please help me if you are still in this post.
Thanks in advance.
