Ember component POST to Express API gives error

When trying to do a post from a component in my ember app to my express api I am receiving

SyntaxError: Unexpected token V in JSON at position 0

When checking what response I'm receiving in the network inspector on chrome I see

ValidationError: body: Path `body` is required., title: Path `title` is required. undefined

The blogpost.title and .body both return the correct values but the blogpost gives me

adapterError: SyntaxError: Unexpected token V in JSON at position 0 at parse

EmberApp/App/Components/create-new-post/Component.js

export default Component.extend({
  blogpost: null,
  router: inject('-routing'),
  actions: {

    save: function (blogpost) {
      console.log(blogpost.title);
      console.log(blogpost.title);
      console.log(blogpost);

      blogpost.save()
          .then(
            (value) => {
              Ember.Logger.info(value);
              this.get('router').transitionTo('index')
            }
          )
          .catch(
            (err) => {
              Ember.Logger.info('failure to save');
              console.log(err);
            }
          )

    }
  }
});

<form  >
  <p>
    
  </p>
  <p>

  <p>
    <button class="btn btn-primary btn-block" type="submit" value="Save">Publish</button>
  </p>
</form>

EmberApp/App/routes/createpost.js

import Route from '@ember/routing/route';

export default Route.extend({
  model() {
    return this.store.createRecord('blogpost');
  }

});

EmberApp/App/templates/createpost.hbs

<div class="container">
  <div class="col-sm-12 pull-left">
    
  </div>
</div>

I have confirmed that the api route for post is working with postman so I'm not sure what the issue is with ember.
