Я расширил набор политик, включив в них новую политику, что означает, что я добавил цели к политикам, чтобы гарантировать, что запрос нацелен на правильную политику.
вот набор политик xacml:

Поэтому, когда я хочу проверить вторую политику (разрешено ли приложение в Prod), я отправляю запрос, например:

Итак, почему PDP сбивается с толку из-за этой одной политики (которая на мой взгляд выглядит так же, как и другая, которая работает правильно .... да, я получаю разрешение, когда приложение находится в списке в политике)?
почему он считает, что атрибут цели полностью отсутствует (вместо того, чтобы иметь неправильное значение)? И почему он делает это для атрибута condition?
