Summary

A link with a bad id — mistyped, stale, or truncated — could break a whole page rather than saying the thing was not there. Opening /projects/<id>/taxa/lists, for example, replaced the project view with "Something went wrong! Cannot read properties of undefined (reading 'length')", and the only way out was to navigate away by hand.

This PR makes every detail link that carries an id behave the same way: if the id cannot be a real record, the app says "Not found" in the dialog or page where the record would have appeared, and the list behind it keeps working. Nothing changes for a valid link.

List of Changes

# What changes for the user How
1 A detail link with an id that is not a record number shows "Not found" instead of breaking the page New isDetailRouteId helper (a positive integer, nothing else); each detail dialog or page skips the request and shows the existing error state
2 Applied to every detail route that takes an id Taxa, occurrences, jobs, deployments, sessions, exports, pipelines, algorithms, processing services, taxa lists, and the taxon shown inside a taxa list
3 An invalid taxa-list id no longer sends a broken filter to the server The species query for that page now receives no list filter instead of the invalid one, which was returning 500s
4 A view waiting on a request it has deliberately not made no longer shows a spinner that never resolves useAuthorizedQuery reports isLoading: false when a caller passes enabled: false

Related Issues

Found while reviewing the taxa-list work for #1424; independent of it.

Detailed Description

Why a bad id could break the page rather than 404. The detail routes accept any string, so /taxa/lists made the app request /api/v2/taxa/lists/. That is a real endpoint — the taxa lists collection — and it answers 200 with a paginated envelope. The dialog built a taxon out of {count, next, previous, results}, every field came back undefined, and the first component to read one threw. Other invalid ids were already fine: /api/v2/taxa/foo/ and /api/v2/taxa/99999999/ both return 404, which the dialogs already display. The failure needed an id that collides with a sibling collection path, so the fix belongs on the id rather than on the word "lists": any later addition such as /occurrences/summary/ would bring the problem back.

The spinner that never resolves. React Query v4 removed the idle status, so a query created with enabled: false reports isLoading: true until it runs. Disabling the fetch for an invalid id therefore produced a blank, permanently hidden dialog instead of the not-found message. useAuthorizedQuery now reports isLoading: false when a caller explicitly passes enabled: false; queries that do not pass it are untouched. Of the fourteen call sites that do, thirteen pass enabled: !!id, and the fourteenth (useUserInfo, disabled when logged out) has no consumer of its loading flag.

Several use*Details hooks took id: string with no way to skip a request; they now take string | undefined and skip when it is missing, which is what the two hooks that already supported it did.

Known and left alone. On a taxa-list page with an invalid id the species query still fires once, unfiltered, before the not-found branch renders; the result is discarded. Gating it needs an enabled flag on a hook that has none, which is more change than this bug warrants. The breadcrumb on that page also keeps its "Loading data..." label in the not-found state.

How to Test the Changes

Unit tests cover the helper (12 valid; lists, foo, 1.5, -1, " 1", "0", empty and undefined invalid) and the loading-state fix. The frontend suite passes (62 tests), along with tsc --noEmit, eslint and prettier.

By hand, in any project:

  1. /projects/<id>/taxa/lists shows a "Not found" dialog over the taxa list, with no console errors. Before this change it replaced the page with an error.
  2. /projects/<id>/taxa/<a real taxon id> still opens the taxon as usual.
  3. /projects/<id>/taxa-lists/foo shows a not-found page rather than a run of 500s.
  4. /projects/<id>/occurrences/notanumber shows a "Not found" dialog over the occurrence list.

Deployment Notes

None. Frontend only, no migration, no settings.

Summary by CodeRabbit

  • Bug Fixes

    • Invalid detail-route IDs no longer trigger unnecessary data requests.
    • Detail views now display a clear “Not found” message for invalid or missing IDs.
    • Disabled data requests correctly report that loading has finished.
    • Detail pages continue to show backend errors when valid requests fail.
  • Tests

    • Added coverage for route-ID validation and disabled-request behavior.

React Query v4 has no idle status: a query created with enabled: false
and never run keeps status 'loading' forever, so isLoading stays true
even though nothing is fetching. A details dialog that skips its fetch
on purpose (no id to look up yet) needs isLoading to settle to false
instead of spinning indefinitely.

Detail routes such as taxa/:id? key their dialog off a database
primary key, so a route id that is not a positive integer can never
be one. Adds the shared predicate and the "Not found" copy the
upcoming route guards will use.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Claude-Session: https://claude.ai/code/session_01TngW6AshkUEhNp9D6z3U9Z
Opening /projects/:id/taxa/lists rendered the whole project view as
the error boundary's crash screen instead of a not-found state. The
route taxa/:id? accepts any string, so id became "lists"; the details
dialog then fetched /taxa/lists/, which is a real endpoint (the taxa
lists collection) and returned 200 with a paginated payload the
dialog cannot read as a single taxon, throwing on an undefined field.

Ids for these detail routes are always database primary keys, so a
route id that is not a positive integer is a not-found, not a request
to make. Each details dialog and page now skips its fetch for a
non-numeric id (isDetailRouteId) and shows the existing not-found
error state instead of crashing. Covers taxa, exports, algorithms,
processing services, pipelines, deployments, jobs, occurrences,
taxa lists and taxa list details, and sessions.

Keep missing IDs disabled when enabled is true.

useJobDetails(undefined, true) enables useAuthorizedQuery. Its queryFn then calls axios.get with the URL /jobs/undefined/. Require a valid ID before applying the optional flag. Add a regression test for this combination.

Disable the species query for invalid taxa-list IDs. getFetchUrl omits taxa_list_id when validId is undefined, so the filter is not serialized. However, TaxaListDetails calls useSpecies before the invalid-route return. useSpecies passes no enabled value to useAuthorizedQuery, so React Query runs the request without a taxa_list_id filter. Add an enabled option to useSpecies and pass !!validId from this page.

Why would we have undefined IDs? can we return a different response from the backend instead if an algorithm is not found and handle that?
