Receiving an odd error on run of script

[orawalters]

I've put in the code according to the documentation the only thing I did was ad templating. Can anyone see what's wrong?

    <?php
    error_reporting(E_ALL);
    ini_set("display_errors", 1);
    date_default_timezone_set('EST');
    # Include the API
    require 'vendor/autoload.php';
    require 'lib/SendGrid.php';
    require 'html2text.php';
    # Instantiate the client.
    $sendgrid = new SendGrid('...', '...', array("turn_off_ssl_verification" => true));
    $html = $_POST["message"];
    $text = convert_html_to_text($html);
    $date = date('l, F jS ');
    # Make the call to the client.
    $email = new SendGrid\Email();
    $email
        ->addTo('...')
       # ->addTo('...') uncomment on final script
        ->setFrom('...')
        ->setSubject('New reminder for ' . $date)
        ->setText($text)
        ->setHtml($html)
        ->addFilter("templates", "enabled", 1)
        ->addFilter("templates", "template_id", "a874a34a-a9b7-460b-a5ae-7226e68da0f1")
    ;
    print '<h1>Sent successfully</h1>';
    ?>
