I just started using the base_url to put the webserver behind nginx proxy under
a sub-path, elg [http://domain.com/airflow]
I've tried following the docs for nginx proxy, i.e.
[webserver]
base_url = [http://localhost/airflow|http://airflow-web/airflow]
I've also tried setting the base_url to the fully-qualified endpoint:
base_url = [https://example.com/airflow|https://domain.com/airflow]
Neither work, both give the TypeError exception.
If I remove the sub-path:
base_url = [https://example.com|https://domain.com/]
then the app starts and runs ok and i can access it on the host but not through
the proxy.
