# n8n workflow manifest
|
|
|
|
Source of truth for the four canonical Fleet Ops n8n workflows. Definitions in this
|
|
directory are cleaned exports of the live workflows on `https://n8n.itworx.tech` —
|
|
credential values are never embedded; nodes reference named n8n credentials instead. Run
|
|
`n8n/workflows/check_drift.py` to compare a live workflow against its repo definition.
|
|
|
|
## 1. Fleet Ops — Vehicle Return Orchestration
|
|
|
|
| Field | Value |
|
|
|---|---|
|
|
| File | `fleet-ops-vehicle-return.json` |
|
|
| Purpose | Orchestrate the post-return follow-up (cleaning vs. attention-required) once Fleet Ops emits a `vehicle.returned.v1` outbox event, and report the result back to Fleet Ops. |
|
|
| Trigger | Production webhook, `POST /webhook/mobilityops-return`, Header Auth (`Fleet Ops Webhook Trigger Token`) |
|
|
| Event contract | `contracts/events.schema.json`, `event_type: vehicle.returned.v1` (envelope: `event_id`, `event_type`, `occurred_at`, `correlation_id`, `aggregate`, `data`) |
|
|
| Required credentials | `Fleet Ops Webhook Trigger Token` (Header Auth, on the trigger); `Fleet Ops Service Token` (Header Auth, on the outbound HTTP call) |
|
|
| Live workflow ID | `mobilityops-return-processing` |
|
|
| Active status (as of 2026-08-04) | Active / Published |
|
|
| Error Workflow | `Fleet Ops — Workflow Error Handler` (wired) |
|
|
| Timeouts / bounded retries | `Record follow-up` and heartbeat HTTP nodes: 15s timeout, retry on fail (3 tries, 1000ms wait) |
|
|
| Execution telemetry | Successful runs POST execution ID and status to `/api/v1/integrations/n8n/heartbeat`; failed runs are registered by the Error Workflow. |
|
|
| Checksum (sha256) | `19f233b6de90a3474010d5495a53c75e969fb5de591e84dd3abcf9635304c1f1` (HTTPS callback definition, 2026-08-21) |
|
|
|
|
## 2. Fleet Ops — Scheduled Data Quality Scan
|
|
|
|
| Field | Value |
|
|
|---|---|
|
|
| File | `fleet-ops-data-quality-scan.json` |
|
|
| Purpose | Periodically (and on-demand) run the Fleet Ops data-quality scan and summarize created-issue counts per rule. |
|
|
| Trigger | Schedule Trigger (hourly, Europe/Brussels instance timezone) + Manual Trigger for on-demand test runs |
|
|
| Event contract | N/A — HTTP-triggered scan call, no inbound event envelope. Request: `POST /api/v1/integrations/n8n/scheduled-scan`, Header Auth. |
|
|
| Required credentials | `Fleet Ops Service Token` (Header Auth, on the scan HTTP call) |
|
|
| Live workflow ID | `mobilityops-scheduled-quality-scan` |
|
|
| Active status (as of 2026-08-04) | Active / Published |
|
|
| Error Workflow | `Fleet Ops — Workflow Error Handler` (wired) |
|
|
| Timeouts / bounded retries | Scan and heartbeat HTTP nodes: 15s timeout, retry on fail (3 tries, 1000ms wait) |
|
|
| Execution telemetry | Every successful scheduled/manual run posts an idempotent heartbeat with its n8n execution ID. |
|
|
| Checksum (sha256) | `057bfe27ea7e2b497c57dec2a5967cad2960170a5c17535021f4480e63a6073d` |
|
|
|
|
## 3. Fleet Ops — RAGcore Procedure Sync
|
|
|
|
Fully built with 7 real nodes: Schedule Trigger → List procedures → Prepare uploads →
|
|
Upload to RAGcore → Summarize sync result → Report sync result → Report heartbeat.
|
|
|
|
**Published/active as of 2026-08-05**, once RAGcore itself went live (see
|
|
`PROJECT_STATE.md`'s "RAGcore actually went live" entry): the workflow's `RAGcore Sync
|
|
Token` credential had also gone stale from the same credential rotation, so a fresh,
|
|
dedicated, minimally-scoped (`sources:sync` only) credential was minted before
|
|
publishing. Verified with a real manual execution first — 33 procedures synced, 0
|
|
failed, Fleet Ops registered the result (`execution_id` 159) — before flipping it to
|
|
run unattended on its daily schedule.
|
|
|
|
While validating this workflow (2026-08-05), found and fixed a real defect: the "Report
|
|
sync result to Fleet Ops" node's three body-parameter expressions each had a stray
|
|
trailing `}}` (e.g. `={{ $json.execution_id }} }}` instead of `={{ $json.execution_id
|
|
}}`), which would have sent malformed values on every real run. Fixed via `n8n
|
|
import:workflow` (the safe CLI path — not the REST API, which caused a prior wipe
|
|
incident in this environment) against the same live workflow ID, keeping it inactive;
|
|
re-exported and verified the fix applied with no other change (7 real nodes; the cleaned
|
|
repository export intentionally remains `active: false` so importing cannot start work
|
|
before credentials are wired). Also found and fixed a second gap: `settings.errorWorkflow` was unset
|
|
(workflows 1-2 wire `"errorWorkflow": "Xppn2rAEqUuyiCJF"`, workflow 3 did not) — wired it
|
|
the same way via the same CLI import path, re-verified.
|
|
|
|
| Field | Value |
|
|
|---|---|
|
|
| File | `fleet-ops-ragcore-procedure-sync.json` |
|
|
| Purpose | Sync the trilingual procedure documents from Fleet Ops into RAGcore as source documents, keeping stable per-document IDs and skipping unchanged content. |
|
|
| Trigger | Schedule Trigger (daily at midnight) |
|
|
| Event contract | N/A — HTTP-triggered sync. Reads `GET /api/v1/integrations/n8n/procedures`, uploads via RAGcore's `POST /v1/uploads`, reports via `POST /api/v1/integrations/n8n/procedures-sync-result`. |
|
|
| Required credentials | `Fleet Ops Service Token` (Header Auth, on the procedures-list and result-report calls); `RAGcore Sync Token` (Header Auth, `sources:sync` scope, on the upload call) |
|
|
| Live workflow ID | `6wbkc4d1AouGpmWT` |
|
|
| Active status (as of 2026-08-05) | **Active / Published** |
|
|
| Error Workflow | `Fleet Ops — Workflow Error Handler` (wired) |
|
|
| Execution telemetry | Successful syncs report both the bounded sync result and the canonical workflow heartbeat. |
|
|
| Checksum (sha256) | `4afd46b6ef57b7e0a4705611732506d7fcc2a37567266847991b85050e1d37c3` |
|
|
|
|
## 4. Fleet Ops — Workflow Error Handler
|
|
|
|
Central technical workflow attached to all three other Fleet Ops workflows (1, 2, 3) via
|
|
n8n's per-workflow "Error Workflow" setting. Receives n8n's
|
|
standard Error Trigger payload, derives a bounded/secret-free failure report (safe error
|
|
category, truncated summary, no stack trace, no headers/tokens), and POSTs it to Fleet
|
|
Ops, which registers an audit event idempotently keyed on `execution_id`.
|
|
|
|
| Field | Value |
|
|
|---|---|
|
|
| File | `fleet-ops-error-handler.json` |
|
|
| Purpose | Central error notification target for all other Fleet Ops n8n workflows |
|
|
| Trigger | Error Trigger (fired by n8n when an attached workflow's execution fails) |
|
|
| Event contract | None inbound (n8n's built-in error-trigger payload); outbound `POST /api/v1/integrations/n8n/workflow-error`, Header Auth, body: `workflow_id, workflow_name, execution_id, failed_at, error_category (timeout\|authError\|connectionError\|httpError\|validationError\|unknown), error_summary, trigger_context, correlation_id, attempt, retry_action` |
|
|
| Required credentials | `Fleet Ops Service Token` (Header Auth, on the outbound HTTP call — same credential workflows 1-2 use) |
|
|
| Live workflow ID | `Xppn2rAEqUuyiCJF` |
|
|
| Active status (as of 2026-08-04) | Active / Published |
|
|
| Error Workflow (on itself) | `- No Workflow -` (deliberately unset — prevents a recursive error loop) |
|
|
| Execution telemetry | A successfully handled failure posts its own execution heartbeat after registering the target failure. |
|
|
| Checksum (sha256) | `57e6c1206b1be4522d88a5983f53b2ddf94f8d6e55c1b7be8c397f75e46412da` |
|
|
|
|
Validated this round: mock-data run (Error Trigger pinned to a realistic payload)
|
|
produced a real `200 {"status":"registered", ...}` from the live Fleet Ops server;
|
|
re-running the identical payload produced `"status":"already_registered"`, confirming
|
|
execution_id idempotency. A genuine induced failure (temporarily pointing workflow 2's
|
|
HTTP node at a nonexistent path, then reverting) confirmed workflow 2 itself fails
|
|
correctly against a broken endpoint and recovers cleanly once reverted; n8n's Error
|
|
Workflow trigger did not fire for that *manual* "Execute workflow" editor run — n8n only
|
|
invokes Error Workflow for unattended/production trigger executions, not manual test
|
|
runs from the editor. This is a known limitation of the live-validation evidence for this
|
|
round: the mock-data path exercises the same nodes/logic and the real Fleet Ops
|
|
endpoint, but a fully automatic (schedule- or webhook-triggered) failure cascading into
|
|
this handler was not observed live.
