CSRF vuejs-axios not working

Hi,
Spending hours to post some vuejs - axios data to my codeigniter.

PHP Code:

axios({
method: 'post',
url: 'http://puppyplaza.dev/api/saveprofile',
data: {
    csrf_token: 'b2897db3f48b2c08c7313f280b290eb3',
    email: this.profile.email
}
}) 


In my config the token name is "csrf_token".  csrf_regenerate is FALSE just to simplify the problem.
http://puppyplaza.dev/api/save profile is a for now a simple controller to display the result (on my localhost)

PHP Code:

    public function saveprofile()
    {
        $data = array('data'=> 'data to send back to browser');
        $this->load->helper('security');
        //$this->input->post('csrf_token'); 
        //$csrf =  $this->security->get_csrf_hash();
        $this->output
        ->set_content_type('application/json')
        ->set_output(json_encode(array('data' => $data, 'csrf' => $csrf)));

    } 


With Jquery it works
data: {'csrf_token':'b2897db3f48b2c08c7313f280b290eb3'},

With axios it wont!




Please, please anyone!?
