FleetAI has no position-history endpoint, so to answer "where was this
rep's vehicle at 10:20 last Tuesday" we have to record it ourselves.
An n8n Schedule Trigger calls POST /api/v1/tracker/poll every 5 minutes
during working hours; a nightly run derives stops and prunes.
poll: */5 6-18 * * 1-5 (the working-hours window lives in the
cron, not in app settings — disabling
the workflow is the off switch)
nightly: 30 2 * * *
One getTokenBaseLiveData call covers the whole fleet per cycle, and only
genuinely new GPS fixes are written: dedupe keys on (vehicle_no,
fixed_at) against the newest fix already held. A parked tracker keeps
re-reporting the same GPSActualTime, so without this a 5-minute cycle
would store the same row a dozen times an hour.
Raw breadcrumbs are pruned at 35 days; derived rep_stops are kept
indefinitely, since a stop is small and is what reports actually ask
about.
Two bugs found by running this against the real stack, neither of which
the unit tests could have caught:
- FakeTrackerAdapter derived its fix time from Date.now(), so every poll
looked like new movement. It could never reproduce a parked vehicle —
the exact case dedupe exists for — and made the poller look correct
while storing a duplicate every cycle. The fake now quantises its fix
time to a bucket, so repeated polls inside one window return an
identical fix.
- PocketBase's filter parser silently matches NOTHING against an
ISO-8601 `T` separator. `fixed_at >= "2026-09-06T00:00:00.000Z"`
returned 0 rows where the space-separated form returned 2, with no
error either way — the rollup would have derived no stops and the
prune deleted no rows, both reporting success, forever. Fixed with a
`pbDate()` helper matching the existing convention in
boss-dashboard-service.ts and order-delivery-note-link-service.ts.
Verified end to end on :4001 against the live PocketBase: three
consecutive polls returned stored=0/duplicates=1, and the nightly rollup
went from vehicles=0 to vehicles=1 once the date format was fixed. Test
rows were removed afterwards.
