(I created an Apache JIRA account to try report this there, but in the Create Issue dialog box the Airflow project was not among the many options.)
Airflow version: 1.10.9 Description: A rebuild of the docker image we use to run Airflow upgraded the version of SQLAlchemy to 1.3.16, which causes the following exception when starting the airflow webserver: Traceback (most recent call last): File "/usr/local/bin/airflow", line 37, in <module> args.func(args) File "/usr/local/lib/python3.7/site-packages/airflow/utils/cli.py", line 75, in wrapper return f(*args, **kwargs) File "/usr/local/lib/python3.7/site-packages/airflow/bin/cli.py", line 900, in webserver app = cached_app_rbac(None) if settings.RBAC else cached_app(None) File "/usr/local/lib/python3.7/site-packages/airflow/www/app.py", line 233, in cached_app app = create_app(config, testing) File "/usr/local/lib/python3.7/site-packages/airflow/www/app.py", line 103, in create_app models.Chart, Session, name="Charts", category="Data Profiling")) File "/usr/local/lib/python3.7/site-packages/flask_admin/contrib/sqla/view.py", line 330, in __init__ menu_icon_value=menu_icon_value) File "/usr/local/lib/python3.7/site-packages/flask_admin/model/base.py", line 818, in __init__ self._refresh_cache() File "/usr/local/lib/python3.7/site-packages/flask_admin/model/base.py", line 913, in _refresh_cache self._search_supported = self.init_search() File "/usr/local/lib/python3.7/site-packages/flask_admin/contrib/sqla/view.py", line 581, in init_search if tools.is_hybrid_property(self.model, name): File "/usr/local/lib/python3.7/site-packages/flask_admin/contrib/sqla/tools.py", line 209, in is_hybrid_property return last_name in get_hybrid_properties(last_model) File "/usr/local/lib/python3.7/site-packages/flask_admin/contrib/sqla/tools.py", line 190, in get_hybrid_properties for key, prop in inspect(model).all_orm_descriptors.items() File "/usr/local/lib/python3.7/site-packages/sqlalchemy/inspection.py", line 72, in inspect "available for object of type %s" % type_ sqlalchemy.exc.NoInspectionAvailable: No inspection system is available for object of type <class 'method'> Specifying SQLAlchemy <= 1.3.15 in the requirements.txt file we use to build the docker image fixes the issue. Our requirements.txt file now looks like this: apache-airflow[crypto,mysql,slack] == 1.10.9 pendulum == 1.4.4 requests >= 2.20.0, < 3 SQLAlchemy <= 1.3.15 Our Dockerfile is based on python:3.7-slim Hopefully that lets somebody reproduce the issue. Let me know if there's a way I can submit this bug on JIRA instead, or if there's anything else I can do to help. Regards, Wesley Hill wh...@yext.com
