Keycloak Spring Multitenant Null Pointer Exception

Исходный код из: https://github.com/ineat/spring-keycloak-мультитенант

Запустил Keycloak и добавил области, как указано в файле readme.

Обновлены коды Keycloak Json в соответствующих местах.

Начал весенний проект.

Получил следующие исключения при вызове "http://локальный:8081/мультитенант":
