Braintree не генерирует клиентский токен на эластичном бобовом стебле AWS

Question

Я столкнулся с этой проблемой в приложении Spring Boot, где я получаю исключение нулевого указателя для генерации клиентского токена для Braintree на AWS Elastic Beanstalk, где он отлично работает в localhost. Если кто-нибудь может помочь мне указать на проблему, которая будет высоко оценена.
