Я пытаюсь настроить систему регистрации SMS с помощью AWS Pinpoint, Lambda, API Gateway и SNS. Однако всякий раз, когда я пытаюсь обработать данные, используя ajax с их примером, он каждый раз выдает ошибку.
Я следовал приведенному здесь руководству, чтобы настроить всю систему: https://docs.aws.amazon.com/pinpoint/latest/developerguide/tutorials-two-way-sms.html
Я протестировал обе функции Lambda в AWS, и они отлично работают. Однако при отправке данных через форму я не вижу запроса API.

Я ожидаю, что он отправит запросREST API, который запускает функцию Lambda для отправки SMS-сообщения. Однако, это не заканчивается отправкой запроса. Я также попробовал общее тестирование REST API с помощью Postman, которое затем выдает мне ошибки в функции Lambda. Я протестировал с помощью веб-сайта тестирования REST API, и он говорит, что сообщает об ошибке HTTP 0. И здесь упоминается, что у меня включен CORS, и он уже включен в моем API.
Пожалуйста, дайте мне знать, если у вас есть какие-либо идеи!
Спасибо.
