Проблема при проверке Google CAPTCHA на angularjs на сервере nodejs

Question

Я пытаюсь подтвердить вход в систему с помощью Google CAPTCHA на angularjs с nodejs сервером, когда я пытаюсь войти в систему с помощью Re-CAPTCHA, я получаю http 405 ошибка не найдена, и когда я вхожу без кода CAPTCHA Проверка Я получаю следующие ошибки в консоли браузера -
