У меня есть специальный регистратор с приведенной ниже структурой. Он использует dictConfig для чтения файла default.json для регистратора. Он работает нормально, но когда я захотел вложить его в корень проекта, при его импорте возникла ошибка. Есть ли причина, почему это может произойти? Я дважды проверил путь и убедился, что он правильный.
Исходная структура
tealogger/
- configuration/
- default.json
- __init__.py
- formatter.py
- ...
Вложенная структура
projectroot/
- tealogger/
- configuration/
- default.json
- __init__.py

Сокращенная версия кода приведена ниже, полную версию можно найти на GitHub. Полученный мной результат можно воспроизвести с помощью ветки development-nest. Я просто запустил оболочку Python и запустил программу импорта в корне проекта.
