How to add new comment in wp-api using AngularJS?

I want to add new comment to wordpress's post in WP-API using angular js. And this is my function to do that:

WPService.setComment = function(comment) {
    var data = [
        {
            'author_email'  : comment.email,
            'author_name'   : comment.name,
            'author_url'    : comment.url,
            'content'       : comment.body,
            'post'          : comment.post
        }
    ];
    return $http.post('wp-json/wp/v2/comments', data[0]).success(function(res, status, header) {
        console.log('comment posted...!');
    }).error(function(err) {
        console.error(err);
    });
}

But it doesn't work properly. How can I add new comment in this way?

UPD #1 It seems angular can't enter to error block and return errors before that. These are errors:
