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

try this one:

pm.test("your-value is not null", function () {
var jsonData = pm.response.json();
pm.expect(jsonData.your_value).not.eql(null);
});
