Django - Использование mysql.connector.django дает TypeError: не все аргументы, преобразованные во время форматирования строки

При использовании Django с mysql-connector-python и представлениями администратора и при попытке вывести данные из одной из таблиц страница завершается с ошибкой TypeError: not all arguments converted during string formatting.API Django Rest Framework работают и возвращают данные для одной и той же таблицы.

Кто-нибудь видел это раньше?Любые идеи, чтобы это исправить?

Та же база кода работает на сервере Postgres.

Версии: 

django==2.0.13
djangorestframework==3.8.2
mysql-connector-python==8.0.5

Вам необходимо выполнить обновление до последней версии Connector / Python (8.0.16 в настоящее время). 

pip install --upgrade mysql-connector-python
...
