CSRF Token missing in POST

[chefsoo]

React front end, trying to post to the server side.
However I get an "Error: CSRF token missing"

import Cookies from 'js-cookie';
....
           async submitForm() {
        console.log('submitting form');
        console.log(this.state);
        const formData = {
            checkinData: this.state.checkinData,
        };
       const xsrfCookie = Cookies.get('XSRF-TOKEN');
        const headers = new Headers({
            'XSRF-TOKEN': xsrfCookie,
            '_csrf': xsrfCookie,
        });

        console.log("formdata",formData)
        const res = await fetch('/postAttempts', {
            method: 'POST',
            headers,
            credentials: 'include',
            body: JSON.stringify(formData),
        })

From the controller

exports.postAttempts = function(req, res) {
  console.log(req);
  console.log(req.body);

  res.json({data: 'hi'});
};

Am I incorrectly setting the csrf token in the header?
