Noël BARDELOT commented on AIRFLOW-6865:
----------------------------------------
First thing, with import flask being the declaration of flask (with lowercase f
as in the error log), it seems to mean that the whole flask module is not
available at the time the before_request annotated method is called.
Second thing, I don't understand why I see packge
/usr/local/lib/python3.7/site-packages/airflow/www_rbac/app.py being used while
I'd expect www/app.py -> probably some Python magic here...
