ValueError: invalid literal for int() with base 10: ''
Django продолжает выдавать следующее при развертывании проекта (ошибка во время миграции при запуске heroku run python manage.py migrate)
ValueError: invalid literal for int() with base 10: ''
Я хочу развернуть этот проект на heroku, он успешно работает до
git push heroku master --forc
но при переносе базы данных с помощью этой команды:
heroku run python manage.py migrate
выдает ошибку valueerror.
где я допустил ошибку?
Если вы можете предоставитьлюбая помощь, я был бы очень признателен.
