When loading the existing schedule failed, the schedule dialog opened as if nothing were scheduled, so a user could schedule a duplicate action.

What was wrong

ScheduleDialogPresenter.load() caught every error and left entry as null, the same value it uses for "nothing scheduled". The dialog loads the schedule in its formData callback, and then showed the empty form with "Schedule Publish". The user saw no sign of the failure. #5960 fixed the same pattern for schedule() and cancel() and left load() as it was.

What changed

  • load() clears loading and rethrows, like schedule() and cancel(). When nothing is scheduled it still resolves with entry set to null, so the two cases stay distinct. IScheduleDialogPresenter.load documents this.
  • useScheduleDialog's formData catches the rejection, shows the message as a warning toast and closes the dialog. Returning the form there would put back the old problem. Rethrowing would leave the dialog spinning, because Dialog doesn't handle a rejected formData.
  • useScheduleDialog is the only caller of load().

Testing

  • ScheduleDialogPresenter.test.ts gains two tests: a failed load rejects, clears loading and leaves no entry; a "nothing scheduled" load resolves with no entry. The failure test fails on the old code. All 6 tests pass, and app-scheduler typechecks.
  • Checked in the admin:
    • Normal load: "Schedule publish" on a product opens the form as before.
    • Failed load: with GraphQL requests blocked in the browser, the dialog closes straight away and shows "Network error: Failed to fetch" as a warning toast.

Failed schedule load shown as a warning toast

6.5.0 has the same code. The same fix for 6.5.0 is #5995.

Summary by CodeRabbit

  • Bug Fixes
    • Schedule loading errors now surface as warnings instead of leaving the dialog open with an empty form.
    • The dialog’s loading state is cleared when a load fails. A successful load with no scheduled item continues to show an empty entry.

ScheduleDialogPresenter.load() caught every error and left the entry
empty. The dialog then showed the form as if nothing were scheduled, so
a user could schedule an action that already existed.

load() now clears loading and rethrows, as schedule() and cancel() do
since #5960. The dialog's formData catches it, shows the error as a
warning toast and closes the dialog instead of offering the form.
"Nothing scheduled" still resolves with the entry set to null.

🚓 Slop Cop

⚠️ 1 thing(s) worth a look before merging.

Small, focused fix matching its stated intent; only a minor type-safety nit found in the new catch block."

📏 Code-style rule checks

🟡 Low — Catch variable 'error' used without type narrowing

packages/app-scheduler/src/presentation/scheduleDialog/useScheduleDialog.tsx: catch (error) then error.message is accessed directly; error is typed unknown by default in TS catch clauses, so this would normally fail type-checking unless error is implicitly any here or narrowed elsewhere. Worth double-checking this compiles cleanly (PR claims typecheck passes), but it's a fragile pattern since a non-Error throw would break it.

Automated, non-blocking heads-up from an LLM. It can be wrong — use your judgment. Regenerates on every push.

📝 Walkthrough

The schedule dialog presenter now rethrows scheduled-action load errors after resetting loading. The dialog hook warns on failure, closes and clears the dialog callback when available, and returns empty form data. Tests cover failed loads and successful loads with no scheduled item.

The load contract documents rejection on failure and a null entry when no item is scheduled. The presenter rethrows gateway errors after clearing loading. The hook warns and handles dialog cleanup on failure. Tests cover failure and no scheduled item.

Change: Bug fix

Merge Risk: 🔵 Low · up to 10c12

For some failed schedule lookups, the warning toast can have no useful title, although the dialog closes. This is a bounded feedback issue, so merge risk is low.

Use a fallback for empty or missing rejection messages.

For a non-200 response, FetchGraphQLClient throws an object whose message comes from the response JSON. That object can reach this catch with an empty or missing message, so the warning toast can have no useful title. Preserve a non-empty string and use a fallback otherwise.
