Gives agents a playbook for Airflow DAG runs that never finish: bounded waits, detecting the wedged task, and escalating instead of polling forever. Use when an agent waits on a DAG run that sticks in running. Not for runs that fail fast.
Cleans up duplicate DAG runs from an Airflow backfill: why backfills double-create runs, how to delete the extras safely, and how to backfill without duplicates next time. Use when a backfill produced overlapping or repeated runs. Not for normally scheduled duplicate runs.
Vectle found the following relevant skills: - airflow backfill catchup false vs manual runs - Airflow backfill tasks stuck in No status: scheduler starves backfill runs - …
Problem outcome: unknown
Public search query: airflow backfill created duplicate dag runs, how to fix

Fixes MySQL connection drops under Airflow: pool recycling, wait_timeout mismatches, and network instability between workers and the database. Use when tasks fail with this exact OperationalError. Not for wrong credentials or unreachable hosts.

Investigates Airflow tasks that fail with no logs: where logs go per executor, permission problems, and worker crashes before logging starts. Use when the task instance shows failed and the log view is blank. Not for tasks with logs that show a clear error.
Vectle found the following relevant skills: - airflow Variable.get returns None, task failed - Logs enabled but the explorer is empty: path, permissions, restart - [pip in…

Public search query: airflow task failed but logs are empty

Untangles the Airflow executor/task state mismatch: why the executor thinks a task failed while the task instance still says running, and how to reconcile it. Use when you see this exact log message. Not for ordinary task failures.
Vectle found the following relevant skills: - plaid-python ApiTypeError: Invalid type for variable 'category_id' (NoneType) on transactions_get - airflow dynamic task mapping expand reduce

Fixes the Airflow connection-not-found error: where connections live, why a DAG cannot see one, and how environment or secrets-backend mismatches cause it. Use when a task fails with this exact exception naming a conn id. Not for bad credentials inside an existing connection.
Unsticks Airflow DAG runs that sit in running forever: finding the wedged task, clearing zombie tasks, and marking the run correctly. Use when a DAG run never reaches success or failed. Not for runs that are legitimately waiting on long tasks.
Troubleshoots DAGs that vanish from the Airflow UI after a deploy: import errors, dagbag parsing, and the difference between scheduler and webserver views. Use when a DAG was visible before the deploy and is gone now. Not for DAGs that never appeared in the first place.
Fixes slow DAG parsing that times out the dagbag on Airflow startup: finding the slow files, cutting parse-time work, and tuning the parse timeout. Use when the scheduler or webserver logs show dagbag import timeouts. Not for runtime task slowness.
Diagnoses Airflow scheduler and worker heartbeat timeouts: what the heartbeat does, why it stops, and how to tell a dead scheduler from a slow database. Use when tasks stall or the UI shows the scheduler as unhealthy. Not for task-level timeouts inside your DAG code.
Fixes the AirflowSensorTimeout error: why sensors time out, how to set timeout and poke intervals sanely, and when to replace a sensor with a deferrable operator. Use when a sensor task fails with this exact exception. Not for tasks that time out doing their own work.
Covers running Airbyte syncs from inside Dagster: the community integration, polling for job status, and handling Airbyte connection failures as Dagster events. Use when Airbyte is the EL and Dagster owns orchestration. Not for running Airbyte standalone or debugging Airbyte source connectors themselves.
Vectle found the following relevant skills: - dagster-airbyte breaks on Airbyte community edition 1.7+: use Basic auth path - airbyte-cron: RESOURCE_EXHAUSTED namespace rate limit exceeded
