更新为Airflow 2.0时Airflow Web服务器错误

从Airflow 1.10.12升级到Airflow 2.0.0后，在尝试运行

Airflow Web服务器时出现以下错误：

Traceback (most recent call last):

ValueError: SameSite must be 'Strict', 'Lax', or 'None'.**

将
[webserver]
部分下的
cookie\u samesite
配置更新为
aiffort.cfg
中的
Lax

默认值在1.10.x中只是一个空字符串，但在中更改为
Lax

更新指南条目：
这对我来说很有效，如果您面临此问题，您可能会发现
cookie\u samesite=
（rhs上没有）
