Investigation 2026-08-11

Evidence: UAT log bundles attached to ASSRAFIPI-128 (2026-06-23 collection, covers 06-17→06-23) and SLARAFIPI-47 (2026-01-12 collection). Extracted to /tmp/fk-ticket/<ticket>/logs/. Build confirmed by audit 'system.start' params({"version":"1.9.11.96"}), started 2026-06-17T07:52 UTC, no restart before the incident.

The June incident is NOT the January incident

	2026-01-10 07:40:51	2026-06-18 06:32:49
/waiting-room rendered	yes	yes
websocket upgraded (101)	yes	yes
waiting-room join in vuer_css.log	never, for 85 s	within 0.7 s
waiting-room add in vuer_oss.log	no	yes
durable waiting room held customer	no	yes, 5 m 55 s
operator active role	operator	admin

January genuinely is “the client never joined” — matches Szekeres’s 3G-throttle repro. June is a different defect: the join landed on both servers and the customer sat in the durable waiting room while the operator side never surfaced them.

06:32:49.954 CSS  waiting-room join customer id: 14078 / join rpc
06:32:49.959 OSS  waiting-room add customer id: 14078
06:32:49.960 OSS  waiting-room durable waiting room add customer id: 14078  is new customer: true
06:38:44.692 OSS  waiting-room remove customer id: 14078

The “fix already in devel” claim is unsupported

Both halves of FKITDEV-5721 (connectionStateRecovery) — vuer_oss 4dc0daf91e, vuer_css b4e06b42d — plus FKITDEV-7508 7897facace, are NOT ancestors of .90/.91 and ARE ancestors of .92 and of tag raiffeisen-1.9.11.96. Raiffeisen did receive the fix in 1.9.11.92 and it was running in June. It does not address this symptom.

Customer-side symptoms are misleading, not causal

• Red “Kapcsolati hiba” banner is latched. snackbar-container.js:25-48 shows it on any socket.io Manager error; snackBar.script.js:26-33 arms an auto-hide timer only if (this.hideDelayMS) and the twig sets hideDelay: 0, so no timer is ever created. No connect/reconnect handler hides it. One transient error paints it permanently.
• A transient error is expected: timeout: 1000 is the socket.io Manager timeout (default 20000), and the page opens two sockets — esbuild bundles without code splitting, so layout and page bundles each carry their own SocketService and each calls io(). Matches “both sockets 101” in nginx. Fix a6185aa41 (remove duplicated socket connections) is NOT in the Raiffeisen lineage.
• Blank “Az Ön előtt várakozók száma:” — waiting-room-custom-content.template.twig:72 ships <strong id="counter"></strong> empty. Only the join ack and the waiting-room:changed push fill it. No default, no spinner, no timeout.

Operator side — what is settled and what is not

CONFIRMED, explains customer 14078 entirely: nobody had /waitinglist open between 06:13 and 06:59:41. The operator sat on /customer/14078 the whole time (single tab, proven by socket close-time pairing). /waitinglist was loaded 12 times that day, all from 10.216.1.250, first at 06:59:41.

CONFIRMED defect, but NOT the cause of an empty list: an operator whose active role is admin holds waitingList.view (list renders, HTTP 200) but not videoChat.receiveCall, so the take-call button is display:none (acl.js:16 → WaitingList.js:57-61 → WaitingList.styl:15-16). They see the customer and have no way to answer. agtakacs logged in as admin at 06:12:59; first role-switch to operator is 07:06:50, after every failure.

STILL UNEXPLAINED: customer 14081 — operator loaded /waitinglist at 06:59:41, 11 s after the join, and saw nothing for 3 m 23 s. Queue delivery is role-agnostic in code (CustomerService.js:104 +:108, auth.doIfAuthorized → isAuthorized only; videochat.js:17-41 fresh-load path likewise), and the single per-viewer filter hook waitingList:filter has no Raiffeisen implementation. So the code says 14081 was in the payload.

Ruled out: synchronous throw in CustomerService.js:19-24 (neither WaitingRoom RPC Server Error nor Error sending waiting-room:add event on queue appears anywhere in the bundle; no [ERROR] near 06:32/06:39). Appointment split at waitinglist.script.js:125-145 (appointment key is absent from config/docker.json on customization/raiffeisen, so waitinglist.template.twig:23 never renders the portlet — and the screenshot shows no appointment portlet). Infrastructure: no restarts, no redis errors, no unhandled rejections, operator websocket continuous throughout.

Structural defect worth fixing regardless: the operator list has no periodic reconciliation. WaitingRoomService.js:32’s 10 s waiting-list-sync goes to the MQ queue to CSS for customer queue-position only and never touches an operator socket. A single missed push leaves the list stale until a manual page reload.

Answer to Bence — client console logs already exist server-side

vuer_css ships a client-console→server pipeline: vendored Sentry with a custom transport (sentry.script.js:13-24 → CustomTransport.js:28 → server/web/api/sentry.js:5-14) publishing to MQ queue queue-clienterror-log. Captures console.warn/error/assert, uncaught exceptions and unhandled rejections, tagged with customerId. Kill switch web.disableClientConsoleLogging is absent from the Raiffeisen config → defaults ON.

OSS side: consumed at server.js:487 → ClientErrorLogService → table clienterrorlogs (server/db/model/clienterrorlog.js), customerId indexed, no purge/retention job exists.

SELECT id, "from", event, data, "roomId", "createdAt"
FROM clienterrorlogs WHERE "customerId" = 14078 ORDER BY "createdAt" ASC;

UI alternative: GET /clienterror (gated clientErrors.view, admin only) — paginated, no customerId or date filter. Note the data column is encrypted at rest.

Narrower switch: web.socketioSettings.socketioDebugJs: true writes socket.io errors straight into vuer_css.log. Defect if enabled: server/web/routes/socketio-error.endpoint.js:3-5 never sends a response, leaving the request open until browser timeout.

Non-code options for the customer: chrome://net-export, DevTools “Preserve log”, --auto-open-devtools-for-tabs, localStorage.debug = 'socket.io-client:*,engine.io-client:*'.

Screenshot evidence (all 3 SLARAFIPI-47 images reviewed 2026-08-13)

image1.png — two distinct waiting-room states. Left: “Ügyintézőnk hamarosan fogadja!” (nobody ahead). Right: “Az Ön előtt várakozók száma: 1”. Péter’s own words: only one call, nobody ahead, so the LEFT screen was expected; the RIGHT layout appeared with nothing after the colon. ⇒ The client took the “people ahead of you” branch and rendered an empty value. A missing event would leave the initial state, so this is NOT simply downstream of the absent operator push — it is the signature of position being undefined/null, failing a === 0 check and falling to the else branch. Correction to the section above: the blank counter is its own defect.

image.png (January) vs ASSRAFIPI-128 image.png (June) — the banner is not evidence. Near-identical otherwise (same agtakacs in “KISZOLGÁLÓ ÜGYINTÉZŐK”, same “Jelenleg egyetlen ügyfél sem várakozik”, same blank counter, same sidebar). January has NO red “Kapcsolati hiba” banner — the incident where the join provably never fired. June HAS it — where both sockets were healthy 5 m 50 s. Backwards from a real connection indicator; independent confirmation of the latched-flag reading. Also: the operator panel listed agtakacs beside an empty queue in January too, when she was confirmed in operator role ⇒ that pattern does not discriminate role. Keep role out of any partner-facing answer.

image2.png — customer list, ids 13029–13034 dated 2026.01.12, i.e. two days after the 01.10 incident. Weak evidence of absence.

Client error-log pipeline is deployed but DEAD (verified 2026-08-13)

sentry.script.js is served (200, 299442 B) in both bundles. Across BOTH bundles combined: POST /api/sentry = 0, POST /api/socketio-error = 0, clienterror in OSS nginx = 0. The January bundle proves legitimate app POSTs ARE logged by CSS nginx (/api/device-summary ×38, /api/submit-feedback ×7), so this is not a logging gap. Zero requests reach nginx at all ⇒ the failure is client-side, the fetch never fires. ⇒ Do NOT tell the partner their console logs are already being collected. Strong evidence, not proof (conceivably nothing ever triggered a capture) — the clienterrorlogs query now serves to confirm the pipeline is dead rather than to retrieve evidence. Worth its own ticket either way.

Release lineage anomaly (verified directly on tags)

vuer_oss 4dc0daf91e (FKITDEV-5721): not ancestor of raiffeisen-1.9.11.90/.91, ancestor of .92, NOT ancestor of .93, ancestor of .94/.95/.96. .92 is not an ancestor of .93 in either repo — .93 is a hotfix cut off an earlier base that dropped .92’s content, then .94 restored it. So “shipped in .92” is not safe as a blanket statement about later releases. The incident build .96 does contain it (confirmed on the tag, not just the branch). CAVEAT: the vuer_css clone has no raiffeisen-1.9.11.92/.96 tag (narrowed fetch refspec) — the CSS half was confirmed only against origin/customization/raiffeisen and .95.

Incidental defects found

• /api/socketio-error never responds (vuer_css).
• WaitingRoomGraceService.cancel() clears the timeout but leaves the map entry, so a later grace hit can return position 0 and render as -1.
• waiting-room grace period is waitingRoom.gracePeriodMs = 5000 — explains the 5 s disconnect→leave-rpc gap.
