NullPointerException при выполнении HTTP-вызовов с помощью okhttp3 ⇐ JAVA

[Anonymous]

Я пытаюсь выполнить Http-вызовы из службы Soap, развернутой как военный файл на Glassfish 5.1.0 на удаленном сервере Windows. В момент выполнения Http-вызовов к другим микросервисам из службы мыла я получаю ошибку NullPointerException. В настоящее время я обновил клиент (Okhttp) до версии 3.12.13 и обновил код для использования некоторых TrustCertificates, но проблемы по-прежнему возникают. Это трассировка стека возвращаемой ошибки:
