Airflow webserver terminate because of wrong app context Flask

1

So I had Airflow’s webserver running fine until I created a Flask app within the same project root.

project/
  |
  -airflow_home/ # airflow dags, config, etc...
  |
  -app/
    |
    -__init__.py
    -models.py
    -config.py
    -routes.py
  |
  -manage.py

here is the airflow-webserver error:

airflow[19435]: app = cached_app_rbac(None) if settings.RBAC else cached_app(None)
airflow[19435]: File "/home/airflow/.local/lib/python3.7/site-packages/airflow/www/app.py", line 204, in cached_app
