Debug Dagster Skill
Use when the user reports Dagster UI errors, failed runs, missing jobs,
duplicate daemon heartbeats, or bad partition keys.
Fast Recovery
make stop-dev
make seed-partitions
make dev
Validate Definitions
DAGSTER_HOME="$PWD/.dagster_home" .venv/bin/dagster definitions validate -m dagster_pipeline
Bad Partition Keys
If logs mention partition-articles, p001, titles, or non-article strings:
- Do not retry the old run.
- Run
make seed-partitions.
- Launch a fresh
run_full_pipeline, build_dataset, or real article
materialization.
Duplicate Daemon Heartbeats
Run:
make stop-dev
Wait about a minute if Dagster still reports old heartbeats.
