Проблема с миграцией sql ошибка Общая ошибка: 1215

Question

Я использую Symfony 4 и пытаюсь выполнить миграцию с помощью команды:

php bin/console doctrine:migrations:migrate

Но появляется сообщение об ошибке:

SQLSTATE [HY000]: общая ошибка: 1215 Невозможно добавить ограничения внешнего индекса

Я уже много чего пробовал с кодом, но он все еще не работает
