Axios vs jQuery post CORS issue

When doing a CORS post request, jQuery succeeds but Axios gets a CORS error in the console.

This gets a CORS error

Axios.post(endpoint, { email_address : emailAddress})
      .then(function (response) {
        isSentSuccessful = true;
      })
      .catch(function (response) { 
        errorAnimation();
      });

But this works

    jQuery.post(endpoint, { email_address : emailAddress },
        function(resp){
         isSentSuccessful = true;
        })
        .fail(function(resp){
          errorAnimation();
        });

Am I missing something with Axios? My server is already configured for CORS requests.

Another way to deal with this, especially if it worked in jQuery

var config = {
       headers: {
             'Content-Type': 'application/x-www-form-urlencoded'
       },
       params: {
             email_address: emailAddress
       }
};
axios.post( endpoint, {}, config)
.then(function (response) {
       console.log(response);
})
.catch(function (response) {
       console.log(response);
});

From Homyk comment on Dec 9, 2015, was able to come up with this and it worked.

I was setting up a little API to learn Grails. Doing a POST request, only by changing from jQuery to Axios, I went from getting this:
