Incompatibility with sending bulk SMS (Twilio)

[larnoult]

Hello,

I recently started using sms sendings through Twilio. Although single SMS works fine, I noticed a fatal error upon bulk sms sending. Enabling debuging, I caught that error:
Fatal error: Uncaught TypeError: Argument 1 passed to Civi\Aws\Subscriber\Mailing::getEmail() must be of the type string, null given, called in /home/parlemon/www/wp-content/uploads/civicrm/ext/aws-master/Civi/Aws/Subscriber/Mailing.php on line 134 and defined in /home/parlemon/www/wp-content/uploads/civicrm/ext/aws-master/Civi/Aws/Subscriber/Mailing.php:209 Stack trace: #0 /home/parlemon/www/wp-content/uploads/civicrm/ext/aws-master/Civi/Aws/Subscriber/Mailing.php(134): Civi\Aws\Subscriber\Mailing->getEmail(NULL) #1 /home/parlemon/www/wp-content/plugins/civicrm/civicrm/vendor/symfony/event-dispatcher/EventDispatcher.php(214): Civi\Aws\Subscriber\Mailing->addTrackingDataHeaders(Object(Civi\Core\Event\GenericHookEvent), 'hook_civicrm_al...', Object(Civi\Core\CiviEventDispatcher)) #2 /home/parlemon/www/wp-content/plugins/civicrm/civicrm/vendor/symfony/event-dispatcher/EventDispatcher.php(44): Symfony\Component\EventDispatcher\EventDispatcher->doDispatch(Array, 'hook_civicrm_al...', Object(Civi\Core\Event\GenericHookEvent)) in /home/parlemon/www/wp-content/uploads/civicrm/ext/aws-master/Civi/Aws/Subscriber/Mailing.php on line 209
Desactivating AWS plugin allowed me to send batch sms finely.
Any fix would be great!
