Ошибка при работе сервера Tomcat 9. SEVERE: дочерний контейнер не был выполнен во время запуска java.util.concurrent.ExecutionException

Question

Я получаю эту ошибку на Tomcat 9. Я пробовал другие решения, которые упоминаются при переполнении стека, но ни одно из них не работает для меня.

Я создаю приложение, используя Spring и Hibernate

Это ошибка, когда я пытаюсь запустить свой проект на сервере
