Как создать узел в OpenText, используя RestAPI - метод POST из PL SQL?

Question

Я пытаюсь создать узел в OpenText, используя RestAPI, метод POST для получения токена аутентификации работает нормально, но вызов POST для создания узла всегда возвращается 400 - Bad Request.

Обязательные параметры для создания узла: type, parent_id а также name,

Любой вклад в то, что может быть не так?

Ниже мой блок кода:
