Hi, Just got the same error while performing the astronomer certification. steps to reproduce: 1. install the astronomer [cli ](https://www.astronomer.io/docs/cloud/stable/develop/cli-quickstart) 2. open a terminal 3. run: `mkdir <your directory name>` 4. run: `astro dev init` 5. open the `Dockerfile` and replace its content with ```bash FROM quay.io/astronomer/ap-airflow:2.0.0-2-buster-onbuild``` 6. open the airflow UI at `http:// localhost:8080` 7. open the `example_dag` expected result: the DAG should be visible actual result: The following error is shown: ```python Traceback (most recent call last): File “/usr/local/lib/python3.7/site-packages/flask/app.py”, line 2447, in wsgi_app response = self.full_dispatch_request() File “/usr/local/lib/python3.7/site-packages/flask/app.py”, line 1952, in full_dispatch_request rv = self.handle_user_exception(e) File “/usr/local/lib/python3.7/site-packages/flask/app.py”, line 1821, in handle_user_exception reraise(exc_type, exc_value, tb) File “/usr/local/lib/python3.7/site-packages/flask/_compat.py”, line 39, in reraise raise value File “/usr/local/lib/python3.7/site-packages/flask/app.py”, line 1950, in full_dispatch_request rv = self.dispatch_request() File “/usr/local/lib/python3.7/site-packages/flask/app.py”, line 1936, in dispatch_request return self.view_functionsrule.endpoint File “/usr/local/lib/python3.7/site-packages/airflow/www/auth.py”, line 34, in decorated return func(*args, **kwargs) File “/usr/local/lib/python3.7/site-packages/airflow/www/decorators.py”, line 97, in view_func return f(*args, **kwargs) File “/usr/local/lib/python3.7/site-packages/airflow/www/decorators.py”, line 60, in wrapper return f(*args, **kwargs) File “/usr/local/lib/python3.7/site-packages/airflow/www/views.py”, line 1861, in tree dag = current_app.dag_bag.get_dag(dag_id) File “/usr/local/lib/python3.7/site-packages/airflow/utils/session.py”, line 65, in wrapper return func(*args, session=session, **kwargs) File “/usr/local/lib/python3.7/site-packages/airflow/models/dagbag.py”, line 171, in get_dag self._add_dag_from_db(dag_id=dag_id, session=session) File “/usr/local/lib/python3.7/site-packages/airflow/models/dagbag.py”, line 227, in _add_dag_from_db raise SerializedDagNotFound(f"DAG ‘{dag_id}’ not found in serialized_dag table") airflow.exceptions.SerializedDagNotFound: DAG ‘example_dag’ not found in serialized_dag table ``` @eladkal ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
