Hi @gagan.4345 and welcome to the community.
I just took a look at what I think you are attempting to do and it appears to be working for me in both v.7.15 and v.7.16 of the application.
This is a snippet of what I am trying based on what I think you are attempting to do as well:
pm.test("Verify status",function(){
var jsonData = pm.response.json();
pm.expect(jsonData[pm.info.iteration].id.toString()).to.equal(pm.iterationData.get("number").toString());
});
Let me know if this is not the case. If not can you provide us some more information and examples of your tests to help us better understand the issue?
Thanks.
