Ошибка веб-сервера Airflow при обновлении до Airflow 2.0

Question

После обновления с Airflow 1.10.12 до Airflow 2.0.0 я получаю следующую ошибку при попытке запустить airflow webserver:

Answer 1

Обновите cookie_samesite config под [webserver] раздел от до в airflow.cfg.

По умолчанию в 1.10.x используется пустая строка, но она была изменена на Laxв https://github.com/apache/airflow/pull/11873 .

Обновление в руководстве: https://github.com/apache/airflow/blob/2.0.1/UPDATING.md#the-default-value-for-webserver-cookie_samesite-has-been-changed-to-lax
