javascript-api add_deal returning 204 (no response data) and not creating the deal

#code `function createContact() { var email_received = document.getElementById('email').value; var contact = {}; contact.email = email_received; contact.first_name = document.getElementById('f_name').value; contact.last_name = document.getElementById('l_name').value; contact.company = "abc corp"; contact.title = "lead"; contact.phone = "+1-541-754-3010"; contact.website = "http://www.example.com"; var address = {"city": "new delhi", "state": "delhi", "country": "india"}; contact.address = JSON.stringify(address); contact.tags = "tag1, tag2"; // Custom fields can be added to contact object as contact.status = "incomplete"; contact.custom_id = "EN001C";

                // Set Email at success of contact creation. But you can set it at failure too.
                _agile.set_email(email_received);

Same for me. Contact is created and set_email worked. When I try to create the deal I get 204 response and no errors but I can't see the deal on the dashboard
