## Установка пользовательских обработчиков исключений { #install-custom-exception-handlers }

Вы можете добавить пользовательские обработчики исключений с помощью <a href="https://www.starlette.dev/exceptions/" class="external-link" target="_blank">тех же утилит обработки исключений из Starlette</a>.

Допустим, у вас есть пользовательское исключение `UnicornException`, которое вы (или используемая вами библиотека) можете `вызвать`.
