   Tests should be passing now - I saw one error which looks like a flaky test:
   ```
   E           sqlalchemy.exc.OperationalError: (_mysql_exceptions.OperationalError) (2006, 'MySQL server has gone away')
   E           [SQL: SELECT dag_run.state AS dag_run_state, dag_run.id AS dag_run_id, dag_run.dag_id AS dag_run_dag_id, dag_run.execution_date AS dag_run_execution_date, dag_run.start_date AS dag_run_start_date, dag_run.end_date AS dag_run_end_date, dag_run.run_id AS dag_run_run_id, dag_run.external_trigger AS dag_run_external_trigger, dag_run.conf AS dag_run_conf 
   ```
