Postman: How to check whether the field is returning null in the Postman automation

Question

I have tried with \"!== null\", but it is returning PASS even when the field is returning 0 or \"\".

Answer 1

I have done similar, this is one part of the code and its works well Check this code

var jsonData = JSON.parse(responseBody);

for(i=0; i environment.Cstartdate;

tests["response body has department name"] = jsonData.data[i].department.name !== null;

}
