Airflow Tutorial: Debugging Failing DAGs with Real-World Error Logs
JeremyCMorgan · x · 2026-08-22
This Airflow tutorial breaks from convention by intentionally building a crashing daily sales data pipeline to simulate real-world scenarios. It walks through the debugging workflow after a DAG fails, including reading logs, locating the specific error line, using the Clear command to reset state, and rerunning the task. Based on Airflow 3.3.0, it provides a local installation setup without Docker, aiming to teach essential troubleshooting skills through deliberate data messiness.
