  <p>This is what i am trying but getting an error:</p>
  
  <pre><code>const jsonData = pm.response.json();
  
  pm.test('Has data', function() {
    pm.expect(jsonData).to.have.property('id');
  });
  </code></pre>
  
  <p>I want to verify - id, givenName, logo, createdAt, UpdatedAt, tags and all are present and want to make a global function so in other tests I can just call it once</p>
