У моєму випадку, крім вищезгаданого повідомлення про помилку, я також отримав попередження нижче:

Відповідно до цього питання , ця проблема трапляється тому, що для MySQL 8.0 є типова схема для MySQL 8.0 utfmb4
.
Насправді я міг повторити помилку, перейшовши з MySQL 5.7 на MySQL 8.0
Я вирішив цю проблему, експортуючи базу даних, повернувшись до MySQL 5.7 та повторно імпортувавши дані. Я також проводив тести на MariaDB 10.3, і це працює чудово.
