John Arnold commented on AIRFLOW-2190:
--------------------------------------
[~elgalu] Glad you got it working. I think avoiding the proxy-pass issue
basically avoids the TypeError, but the TypeError bug still exists. Anyway, my
airflow project got cancelled so not likely I'm going to have time to update
the docs or the code here. Maybe you can pick it up?
