If Else in Postman based on response body-CodePudding

In postman, if i get a responsebody of [] i want to do an "IF" statement but if the response is anything else it will do the "ELSE" statement however, i cannot make it do the "IF" suggesting that jsonData == "[]" is wrong.

postman capture

Problem

Your response is an array, not a String, so you cann't compare jsonData == "[]"

Solution

Check this array whether has length = 0 or not, you can choose one of 2 below approaches.

if (Array.isArray(jsonData) && jsonData.length === 0)

if (Array.isArray(jsonData) && !jsonData.length)
