title: How to iterate through each property element in API response in Katalon studio?
body: <p>I'm writing test script in katalon studio to verify response body of the API.My response body is of format:</p>
  
  <pre><code>{
    "status": "Success",
    "correlationCode": "1234-5678",
    "type": {
      "id": 51247,
      "name": "Student",
    },
    "data": {
      "name": "Sara Nieves",
      "gender": "Female",
      "dob": "1995-08-06",
      "libraryCard": {
        "id": "11178",
        "type": "Seniors"
      },
      "qualifications": [
        {
          "id": "45650986546",
          "name": "Graduate Certificate in Environmental Engineering Management"
        }
      ]
    }
  }
  </code></pre>
  
  <p>I want to verify that none of the elements return 'null' value. Since, the elements returned for the API response are not static(meaning name, gender etc might not get returned every time) therefore, i can't use something like "data.name" to verify if it has null value. So, i want a generic way to loop through each and every attribute returned and check if its value is returned as null or not.</p>
  
  <p>Any help will be much appreciated. Thanks!</p>
