Troubleshooting

Purpose

Canonical operator troubleshooting guide for recurring implemented Narratio failures.

Config file discovery failure

Symptom:

• run, plan, resume, or run-stage fails with config/session not found.

Likely Cause:

• pipeline.yml or session.yml is missing from discovery paths.
• wrong working directory when relying on ./session.yml.

Diagnostics:

pwd
ls -l ./session.yml
ls -l /usr/local/etc/narratio/pipeline.yml /etc/narratio/pipeline.yml

Safe Fix:

• pass explicit --config and --session.
• or place files in documented discovery paths.

Links:

• docs/config.md
• docs/cli.md

Session template rendering failure

Symptom:

• load fails with unresolved placeholder or session_id mismatch.

Likely Cause:

• templated session.yml used without --session-id.
• rendered session_id differs from passed --session-id.

Diagnostics:

narratio plan --session ./session.yml --session-id 2026-04-04

Safe Fix:

• pass --session-id when template placeholders are present.
• ensure rendered session_id matches intended run session id.

Links:

• docs/config.md

Strict YAML decode or validation failure

Symptom:

• config load fails with unknown field or validation error.

Likely Cause:

• typo/stale field name.
• missing required fields or invalid constraints.

Diagnostics:

narratio plan --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04

Safe Fix:

• align fields/values to canonical config reference and examples.

• docs/config.md
• examples/

--artifacts selection failure

Symptom:

• run/resume/run-stage fails with invalid or unknown artifact selection.

Likely Cause:

• --artifacts contains blank names or unknown artifact keys.
• pipeline.scriptorium.artifacts missing while using --artifacts.

Diagnostics:

narratio run --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04 --artifacts player_handout

Safe Fix:

• use configured artifact keys only.
• ensure pipeline.scriptorium.artifacts is defined.

Links:

• docs/cli.md
• docs/config.md

run-stage --artifacts on non-analyze stage

Symptom:

• run-stage fails with --artifacts is only supported for stage "analyze".

Likely Cause:

• --artifacts was used with a non-analyze stage.

Diagnostics:

narratio run-stage --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04 --artifacts session_recap polish

Safe Fix:

• use --artifacts only with run-stage ... analyze.

Links:

• docs/cli.md

Configured artifact dependency/input validation failure

Symptom:

• config validation fails for depends_on, narratio.artifact.<name> source, or artifact output path.

Likely Cause:

• narratio.artifact.<name> source missing matching depends_on key.
• dependency references unknown artifact key.
• dependency self-reference or enabled dependency cycle.
• artifact output path missing/invalid/outside artifacts/ root.

Diagnostics:

narratio plan --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04

Safe Fix:

• ensure artifact-to-artifact inputs have explicit depends_on entries using artifact keys.
• ensure referenced artifacts exist and define valid output_path values.
• keep output paths relative and under artifacts/.

Links:

• docs/config.md
• docs/internal/stage-analyze.md

Required configured artifact input unavailable at analyze time

Symptom:

• analyze fails because configured input source is unavailable.

Likely Cause:

• required upstream configured artifact was not selected/executed this run.
• non-executable dependency output file is missing or invalid on disk.

Diagnostics:

narratio status --manifest /path/to/manifest.json
narratio run-stage --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04 --artifacts player_handout analyze

Safe Fix:

• run analyze with needed artifacts selected.
• or ensure dependency output file exists at configured path and is valid.

Links:

• docs/operations.md
• docs/config.md

Manifest/status path failure

Symptom:

• status fails because manifest path is missing, unreadable, or invalid.

Likely Cause:

• wrong manifest path.
• manifest removed after cleanup.
• --manifest omitted.

Diagnostics:

narratio status --manifest /path/to/manifest.json
ls -l /path/to/manifest.json

Safe Fix:

• use manifest path printed by run, resume, or run-stage.

Links:

• docs/cli.md
• docs/operations.md

Session lock conflict (.lock)

Symptom:

• run fails with lock conflict for session workdir.

Likely Cause:

• another Narratio process is running same session.
• stale lock from interrupted prior run.

Diagnostics:

ls -l {workspace.root}/work/{campaign}/{session_id}/.lock
cat {workspace.root}/work/{campaign}/{session_id}/.lock
ps aux | grep narratio

Safe Fix:

• wait for active run to finish.
• if no process is active, remove only stale session .lock file.

Links:

• docs/operations.md
• docs/internal/workspace.md

Secrets env-dir or credential-env failure

Symptom:

• startup fails loading secrets directory, or stage fails due to missing credential env vars.

Likely Cause:

• invalid pipeline.secrets.env_dir path/permissions.
• required credential env var unset/empty.

Diagnostics:

ls -la /path/to/secrets_dir
env | grep -E 'AUDITA|OBJECT_STORAGE|AWS|SCRIPTORIUM'

Safe Fix:

• fix secrets directory and credential env vars.
• keep secret values out of YAML.

Links:

• docs/config.md

S3-audio prepare failure

Symptom:

• prepare fails in S3 mode (listing/downloading/no audio/backend error).

Likely Cause:

• wrong session.inputs.audio_s3.prefix.
• no .flac files at resolved prefix.
• invalid/missing object-store credentials or backend config.
• mixed local+S3 audio input config.

Diagnostics:

narratio run-stage --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04 prepare

Safe Fix:

• configure exactly one audio source mode.
• verify .flac files and storage access.

Links:

• docs/config.md
• docs/operations.md

Archive promotion/current-pointer failure

Symptom:

• archive fails on required promotion source missing or pointer write failure.

Likely Cause:

• required promoted file absent (including analyze outputs not generated for this run).
• storage upload failed before current/run_id.txt commit marker write.

Diagnostics:

narratio status --manifest /path/to/manifest.json
narratio run-stage --config /path/to/pipeline.yml --session /path/to/session.yml --session-id 2026-04-04 archive

Safe Fix:

• rerun or resume upstream stages to generate required files.
• adjust promotion source/dest rules to match artifacts that must exist.
• retry after storage issue is resolved.
