assert.exists is not a function

I tried it on a functional model and change the function exists not know dependencies": { “express”: “^4.14.0”, “cors”: “^2.8.1”, “body-parser”: “^1.15.2”, “chai”: “^3.5.0”, “mongodb”: “^3.1.3”, “chai-http”: “^3.0.0”, “mocha”: “^3.2.0”, “zombie”: “^5.0.5”, “helmet”: “^3.1.0”, “mongoose”: “^5.2.8”, “x-xss-protection”: “^1.1.0” },

test(‘Every field filled in’, function(done) {

   chai.request(server)
    .post('/api/issues/test')
    .send({
      issue_title: title,
      issue_text: 'text',
      created_by: 'Functional Test - Every field filled in',
      assigned_to: 'Chai and Mocha',
      status_text: 'In QA'
    })
    .end(function(err, res){
     if(err)   console.log( err);
      assert.equal(res.status, 200);
  //   console.log(  res.body.issue_text);
    // console.log( "re"+JSON.stringify( res));
      assert.isDefined(res.body.issue_title,title);
     assert.exists(res.body.issue_text,'text');
        assert.equal(res.body.created_by,'Functional Test - Every field filled in');
       assert.equal(res.body.assigned_to,'Chai and Mocha');
       assert.equal(res.body.status_text,'In QA');
       idtest=res.body._id
      done();
    });

Oh god you are lazy man. Let assume use 4.0. and you don’t have somewhere that must be with new declarations in brackets. So if somebody try that oh that not working so rather use 3.5 version. there is tons of prefabricated solutions or done with 3.5 and someone want add another function … I don’t even believe I must tell you.
