Когда я щелкаю по имени группы DAG или в виде дерева или графического представления для активных групп DAG, я получаю следующую ошибку:
UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 0: invalid start byte
The above exception was the direct cause of the following exception:

Я использую Airflow (версия 1.8.1) с MySQL 8 в качестве базы данных. Эти пакеты работали, когда я использовал sqlite и Oracle.
После некоторого исследования стека переполнения я внес эти изменения в файл конфигурации воздушного потока, но это не решило проблему.
sql_alchemy_conn = mysql+mysqlconnector://<user>:<password>i@localhost/MIAF?charset=utf8mb4
sql_engine_encoding = utf8mb4
Как мне решить эту проблему?
