Flashdata with Sweetalert2

Hi All,


I have problem when I try to combine flashdata with Sweetalert2,

Controller :

PHP Code:

public function social_settings_pro() 
    {
        $disable_social_login = 
            intval($this->input->post("disable_social_login"));
        $twitter_consumer_key = 
            $this->common->nohtml($this->input->post("twitter_consumer_key"));
        $twitter_consumer_secret = 
            $this->common->nohtml($this->input->post("twitter_consumer_secret"));
        $facebook_app_id = 
            $this->common->nohtml($this->input->post("facebook_app_id"));
        $facebook_app_secret = 
            $this->common->nohtml($this->input->post("facebook_app_secret"));
        $google_client_id = 
            $this->common->nohtml($this->input->post("google_client_id"));
        $google_client_secret = 
            $this->common->nohtml($this->input->post("google_client_secret"));

        $this->admin_model->updateSettings(
            array(
                "disable_social_login" => $disable_social_login,
                "twitter_consumer_key" => $twitter_consumer_key,
                "twitter_consumer_secret" => $twitter_consumer_secret,
                "facebook_app_id" => $facebook_app_id, 
                "facebook_app_secret"=> $facebook_app_secret,  
                "google_client_id" => $google_client_id,
                "google_client_secret" => $google_client_secret,
            )
        );
        $this->session->set_flashdata("globalmsg", lang("success_13"));
        redirect(site_url("admin/social_settings"));
    } 


View :

PHP Code:

<?php if ($this->session->flashdata('globalmsg')): ?>
<script type="text/javascript">
  $(document).ready(function() {
  swal({
  title: "Done",
  text: "<?php echo $this->session->flashdata('globalmsg'); ?>",
  timer: 1500,
  showConfirmButton: false,
  type: 'success'
  });
  });
</script>
<?php endif; ?>

I get error like below,

Code:

Uncaught TypeError: Cannot read property 'querySelector' of null
