fix(web): GPX import keeps its route geometry, and GlitchTip stops reporting non-errors - #378
Merged
Conversation
A track-only GPX (Strava, Garmin, most watch exports) was thinned to at most 15 smart waypoints and then re-routed between them, so the imported route lost its actual shape and rendered as long straight legs. The track is the route the file describes, so it now becomes the draft's geometry verbatim, matching what save-to-library already did. ensureEditableShape still densifies on the first edit. Two smaller causes of the same symptom: - processGPXWaypoints downgraded a waypoint to "direct" whenever the Mapbox Matching API failed to answer, turning a rate limit or network blip into straight legs for the whole route. checkNearRoad now reports `unavailable` separately from a definite off-road verdict, and only the latter yields "direct". - The road check ran one request per waypoint with no bound, so a long rtept list fired hundreds of parallel fetches straight into a rate limit. Capped at 6 concurrent. The planner's import button was disabled until the draft had a waypoint, so a GPX could not be opened onto an empty map. It is always enabled now, the empty-state hero offers Import GPX next to Generate loop, and a successful import frames the route instead of leaving the default view.

163 browser events landed in GlitchTip over the last 30 days and roughly two thirds of them described something working as designed. Every one is an unresolved issue somebody has to read, which is what buries the real ones. What the data showed, and what changed: - "Error: Rejected" (40 events, the top issue) was Googlebot failing to register the service worker: 41 of 41 sampled events were Googlebot. Telemetry now stays off for crawler user agents entirely. - ErrorHandler logged each failure and then reported it, and the log line reports itself, so one error filed two unrelated issues: an exception and a message. The log now runs under `withoutTelemetry`. - A 401 is the API answering a question. Anonymous visitors and expired sessions hitting /users/me, /routes and /social/* produced 175 events across five issues. UNAUTHORIZED and FORBIDDEN are no longer reported. - Denied geolocation permission (146 events, fragmented over five issues) is a user's choice, and an unavailable position or a timeout is the weather. All three drop to info; only an unrecognised code is an error. - checkNearRoad reported NoSegment as a warning (93 events). That is the API answering "no road here", which is the function's entire question, so it now counts as a definite off-road verdict, logged at info. This also corrects the previous commit, which classed it as an outage and would have routed genuinely off-road waypoints. - "[MapCanvas] Map error: [object Object]" (48 events) carried no information: the Mapbox event is circular, so it stringified to nothing useful. The message is extracted at the call site, and the logger now digs a message out of error-like objects before giving up. - Message events grouped on their full interpolated text, so one problem split across releases and URLs. They now fingerprint on the static first argument. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01FkuCWJzFY1QktYCNeFztVp
📝 WalkthroughWalkthroughChangesThe routing flow now preserves imported GPX track geometry, distinguishes road-check outages from off-road results, limits concurrent checks, and frames successful imports. The UI adds import actions. Telemetry now filters bot clients, suppresses duplicate reports, improves Sentry grouping, and clarifies diagnostic logging. GPX import flow

Preserve unavailable results for malformed responses and downstream callers.
There are two paths where a failed or invalid road check is converted into a definite off-road result:
- A response such as
{ code: "Ok", tracepoints: [{}] }reaches the missing-location branch and returns{ isValid: false }.GPXServicethen creates adirectwaypoint, even though the response is malformed rather than a definite off-road verdict. Treat missing or invalid tracepoint locations as{ isValid: false, unavailable: true }; keep only null tracepoints andOFF_ROAD_CODESas definite off-road results, with a regression test. WaypointCoordinator.resolveAddCoordmaps every!isValidresult tocheckNearRoadFailed: true, so an unavailable check can surface as the false “Point is too far from any road” error. Preserve theunavailabledistinction through this path.

Add tests for isBotClient.
The new webdriver branch and the navigator === "undefined" branch have no coverage. apps/web/src/lib/telemetry/bots.test.ts tests only isBotUserAgent. Add tests that verify both client classifications before relying on them to suppress telemetry.
As per coding guidelines, **/*.{test,spec}.{js,ts,jsx,tsx}: Write tests for all code and run via bun run test.

Two unrelated fixes found while looking at GPX import, plus the GlitchTip cleanup that came out of it.
GPX import drew straight lines
A track-only GPX (Strava, Garmin, most watch exports) was thinned to at most 15 smart waypoints and then re-routed between them, so the imported route lost its shape. Reproduced against the running app with a 150-point switchback track: before, the drawn line had 15 points; after, all 150, matching the file exactly.
The track is the route the file describes, so it now becomes the draft's geometry verbatim, matching what save-to-library already did.
ensureEditableShapestill densifies on the first edit.Two smaller causes of the same symptom:
processGPXWaypointsdowngraded a waypoint todirectwhenever the Mapbox Matching API failed to answer, turning a rate limit or network blip into straight legs for the whole route.checkNearRoadnow reportsunavailableseparately from a definite off-road verdict.The planner's import button was also disabled until the draft had a waypoint, so a GPX could not be opened onto an empty map. It is always enabled now, the empty-state hero offers Import GPX next to Generate loop, and a successful import frames the route.
GlitchTip was mostly reporting things working as designed
163 browser events in 30 days, roughly two thirds of them non-errors. What the data showed:
Error: RejectedserviceWorker.register(41 of 41 sampled events)Location error: User denied Geolocation[checkNearRoad] … NoSegmentApiDomainError: Unauthorized+ 4 more[MapCanvas] Map error: [object Object]Two structural problems underneath:
ErrorHandlerlogged each failure and then reported it, and the log line reports itself, so one error filed two unrelated issues. And message events grouped on their full interpolated text, so one problem fragmented across releases and URLs.Changes: crawlers no longer initialise telemetry;
ErrorHandlerlogs under a newwithoutTelemetryguard so a failure is reported once with its structured tags; 401/403 are not reported; denied permission, unavailable position and timeout drop to info;MapCanvaspasses the real Mapbox message and the logger digs a message out of error-like objects; message events fingerprint on the static first argument.Expected effect: ~163 → ~55 events per 30 days, and what remains is actionable.
This also corrects the first commit, which classed
NoSegmentas an outage. GlitchTip showed it is the common real answer, soNoSegment/NoMatch/NoRouteare a definite off-road verdict and only transport/auth/quota failures count as unavailable.Verification
checkNearRoadtests were each confirmed to fail without their fix.bun run lintandbun run check-typesclean.Still open (not silenced, worth watching)
