NuklearRabbitandClaude Sonnet 5 e39c0a1dd6 n8n: build and live-validate the Workflow Error Handler (WF4)
New central "Fleet Ops — Workflow Error Handler" workflow (Error
Trigger -> safe-report Code node -> POST to the new /workflow-error
endpoint), wired as the Error Workflow on both existing workflows with
no recursive loop on itself. Live-validated end-to-end against the
real Fleet Ops server (register + idempotent re-register), and via a
genuine induced failure on the scheduled-scan workflow (broken URL,
confirmed failure, reverted, confirmed healthy).

Fixed two real bugs found during live testing: Code node needed
"Run Once for Each Item" (not "All Items") for $json binding, and
every HTTP body field had a stray trailing space from the n8n
code-editor's bracket auto-close that broke datetime/enum validation.

# 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) |
| Checksum (sha256) | `e13a3087269fc97019a7adf6c6a6a4ee4bd354c2dd7167d4966d4753a48e970e` |
## 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) |
| Checksum (sha256) | `cc30b28b07dad9f9908a6ea0c564ec4c2f362a3ed71b7e97a7b6894408bb7e2e` |
## 3. Fleet Ops — RAGcore Procedure Sync
Not yet built. Blocked on a RAGcore application credential (scope `sources:sync`) for the
`fleet-ops` application, to be provided by the project owner. Will sync
`n8n/workflows/fleet-ops-ragcore-procedure-sync.json` against the real RAGcore contract
(`POST /v1/uploads`, `GET /v1/knowledge-spaces`, etc. — see
`contracts/ragcore-contract-assumptions.md` and the live inspection notes in
`docs/live-ai-integration/n8n-current-state.md`).
| Field | Value |
|---|---|
| File | `fleet-ops-ragcore-procedure-sync.json` (not yet created) |
| Live workflow ID | — |
| Active status | Not built |
## 4. Fleet Ops — Workflow Error Handler
Central technical workflow attached to workflows 1-2 via n8n's per-workflow "Error
Workflow" setting (workflow 3 will be wired the same way once it exists). 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) |
| Checksum (sha256) | `d9e2795b917a89a9b4a733e435661585f8011bc97f134d3643dee93ea05b0be6` |
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.
