My app was working fine for about a entire month, but then, after 03/17 (last week) I keep getting this error message after I click on the submit button (my app sends an email with the details on the form using SendGrid). Error message on chrome after I click on Submit button:
myapp.mybluemix.net is currently unable to handle this request.
HTTP ERROR 500
The thing is that I don't remember changing anything substantial (I even tried older versions of my app and still didn't worked), but it looks like it's a Bluemix issue because it works fine on local.
Here is my log with the "cf log" command:

I'm not sure how to interpret this error, please help!
here's a piece of my code:
// If there are no errors, send the email
if (!$errName && !$errEmail && !$errMessage && !$errHuman) {
$message = $sdrmsg;
require 'vendor/autoload.php';
// If you are not using Composer
// require("path/to/sendgrid-php/sendgrid-php.php");
$from = new SendGrid\Email("", "$email");
$subject = "REQUEST";
$to = new SendGrid\Email("email", "email@example.com");
$content = new SendGrid\Content("text/plain", $message);
$mail = new SendGrid\Mail($from, $subject, $to, $content);
$apiKey = 'mykey';
$sg = new \SendGrid($apiKey);
$response = $sg->client->mail()->send()->post($mail);
echo $response->body();
}
Error is- PHP message: PHP Fatal error: Uncaught Error: Call to undefined function SendGrid\mb_convert_encoding()
Resolution: You will have to enable mb_string in your server. Are you using php_buildpack?
mbstring is a supported extension of the php buildpack, but must be enabled explicitly.
