The ingest-health handler returned reporting.v_ingest_health rows straight to
JSONResponse, but last_run_at is a datetime — json.dumps raised TypeError and the
endpoint fell into its except, always returning {"overall":"unknown","endpoints":[]}.
Every other analytics endpoint already routes through jsonable_encoder; this one
didn't. Surfaced when the prod bridge finally got the /health/ingest route.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
|
Stable replacement for the n8n webhooks that fed the Live Position and Fleet
|
|
Trips map dashboards. n8n was acting only as a thin HTTP→SQL proxy; this
|
|
service does the same job directly against the proven reporting.* functions,
|
|
removing n8n's credential-management / reload / version-drift fragility from
|
|
the live-data path.
|
|
|
|
It REUSES the existing stack: ts_shared_rev's psycopg2 pool and DATABASE_URL,
|
|
the same Docker image, the same Coolify deploy. The reporting.* functions
|
|
(already verified to return correct GeoJSON) are the single source of truth.
|
|
|
|
Endpoints mirror the original n8n webhook paths so the only frontend change
|
|
is the base URL (the `N8N_BASE` constant in each dashboard SPA):
|
|
|
|
GET /webhook/live-positions?cost_centre=&acc_status=
|
|
→ { summary, geojson } (reporting.fn_live_positions)
|
|
GET /webhook/live-positions/track?vehicle_number=&hours=
|
|
(alias: /webhook/vehicle-track)
|
|
→ GeoJSON Feature (reporting.fn_vehicle_track)
|
|
GET /webhook/fleet-dashboard
|
|
→ { drivers, cost_centres, cities, vehicles } (filter options)
|
|
POST /webhook/fleet-dashboard body: {period, vehicle_numbers, driver,
|
|
cost_centre, assigned_city,
|
|
start_date, end_date}
|
|
→ trips payload (reporting.fn_trips_for_map)
|
|
GET /webhook/tickets?service_type=&status=&open_only=
|
|
→ { summary, geojson } (reporting.fn_tickets_for_map) — INC/CRQ map layer
|
|
GET /webhook/{inc,crq}-dashboard?cluster=&status=&window=&from=&to=
|
|
→ { window, open, closed, metrics, freshness } (reporting.fn_{inc,crq}_dashboard)
|
|
GET /webhook/{inc,crq}-search?ticket_id=&owner=&cluster=&status=&state=&from=&to=
|
|
→ { count, truncated, limit, state, rows } (reporting.fn_{inc,crq}_search)
|
|
GET /webhook/{inc,crq}-filter-options
|
|
→ { owners, clusters, open_ticket_ids } (reporting.fn_{inc,crq}_filter_options)
|
|
GET /health
