Hello maintainers
A programmatically generated DAG of mine is exploding (the bomb
text-picture) when triggered with following stack-trace
File
"/home/admin/.pyenv/versions/3.7.3/lib/python3.7/site-packages/airflow/models/__init__.py",
line 2392, in has_dag
return getattr(self, '_dag', None) is not None
RecursionError: maximum recursion depth exceeded while calling a Python object
At this stage, I start getting the following stacktrace at
/logs/scheduler/latest/<path/to/my/dag_script.py.log>
File
"/home/admin/.pyenv/versions/3.7.3/lib/python3.7/site-packages/airflow/jobs.py",
line 930, in _process_task_instances
if len(active_dag_runs) >= dag.max_active_runs:
TypeError: '>=' not supported between instances of 'int' and 'NoneType'
I've tried several things without success
- Ascertained that my Airflow LocalExecutor deployment is still intact
(older workflow's DAGs are still running fine)
- Killing and restarting Airflow's scheduler & webserver several times
- airflow initdb
- Checked airflow.cfg file for any discrepancies
------------------------------
I'm using
- Python 3.7.3 (installed via PyEnv <https://github.com/pyenv/pyenv>)
- Airflow 1.10.3 with LocalExecutor
- Linux ip-XXX-XX-XX-XX 4.9.0-8-amd64 #1 SMP Debian 4.9.130-2
(2018-10-27) x86_64 GNU/Linux
