Airflow webserver error when updated to airflow 2.0

After upgrading from Airflow 1.10.12 to Airflow 2.0.0, I get the following error when trying to run airflow webserver:

Update the cookie_samesite config under [webserver] section from to Lax in airflow.cfg.

Default is just an empty string in 1.10.x but was changed to Lax in https://github.com/apache/airflow/pull/11873.

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