Preserve deep-linked report route during onboarding guard redirect by MelvinBot · Pull Request #86390 · Expensify/App

MelvinBot · 2026-03-26T04:19:53Z

Explanation of Change

This is a re-creation of the reverted PR #85556 with identical changes.

When an unauthenticated user visits a direct report deep link (e.g., /r/7075912447943023), signs in as a new account, and gets redirected to onboarding, the deep-linked report route is lost. This happens because handleNavigationGuards in RootStackRouter.ts completely replaces the navigation state when the OnboardingGuard fires a REDIRECT — the state becomes [Home, OnboardingModalNavigator] instead of preserving the existing report route.

This PR modifies handleNavigationGuards so that when a REDIRECT adds a modal route (like the OnboardingModalNavigator), the existing fullscreen/base routes (like the deep-linked report) are preserved instead of being replaced with Home. The navigation state becomes [ReportsSplitNavigator(deep-linked report), OnboardingModalNavigator], so when onboarding completes and the modal is dismissed, the user lands on their deep-linked report.

When no existing fullscreen routes are present or the redirect doesn't include modal routes, the behavior falls back to the previous logic.

When the OnboardingGuard fires a REDIRECT, handleNavigationGuards was replacing the entire navigation state with [Home, OnboardingModalNavigator]. This discarded any existing fullscreen routes, including a deep-linked report that the user was trying to access before signing in. Now we separate the redirect state into fullscreen (base) and modal routes. If the current state already has fullscreen routes and the redirect adds modal routes, we preserve the existing fullscreen routes and layer the modal routes on top. This means the navigation state becomes [ReportsSplitNavigator(deep-linked report), OnboardingModalNavigator] instead of [Home, OnboardingModalNavigator], so when onboarding completes and the modal is dismissed, the user lands on their deep-linked report.

MelvinBot · 2026-03-27T07:51:37Z

The failing check (test (job 1)) is unrelated to this PR.

Analysis: The test tests/unit/CardFeedUtilsTest.ts failed with a SIGSEGV (segmentation fault) — a jest worker process was killed by the OS, likely due to memory pressure in CI. This is a flaky infrastructure issue, not a code error. All 1140 tests that actually ran passed successfully.

Evidence: This PR only changes RootStackRouter.ts and handleNavigationGuardRedirect.test.ts (navigation code). The crashing test (CardFeedUtilsTest.ts) is in a completely different domain (card feed utilities) and has no relation to the PR's changes. The navigation guard test added by this PR (handleNavigationGuardRedirect.test.ts) passed successfully.

Re-running the failing job should resolve this.

+        if (redirectRoute && state.routes[state.index]?.name === redirectRoute.name) {
+            return state;


Compare full redirect target before short-circuiting

This early return only compares the top-level route name, so redirects to different onboarding steps are treated as duplicates once OnboardingModalNavigator is focused. OnboardingGuard computes step-specific redirect paths (e.g., purpose vs employees) but they share the same root navigator name; returning state here skips the reset and also bypasses downstream action handling, which can leave users stuck on an outdated onboarding step instead of being redirected to the newly required one.

Useful? React with 👍 / 👎.

Yeah I really think this is unneeded as well as wrong.

We need this, otherwise multiple onboarding modal will be added when we refresh the app. (multiple navigation actions are fired).

I wanna test comparing findFocusedRoute(state).name === findFocusedRoute(redirectState).name, but got distracted with other things and forget to come back to this 🤦

Wrong this change BTW caused a regression. If you proceed up to accounting stage of onboarding(selecting manage teams) and deeplink to purpose page you are now not correctly redirected to oboarding-account page.

I wanna test comparing findFocusedRoute(state).name === findFocusedRoute(redirectState).name, but got distracted with other things and forget to come back to this

Yep, that's why I say this ^. If we use findFocusedRoute(state).name === findFocusedRoute(redirectState).name, then that won't happen. But there is another problem.

When we open onboarding/purpose by changing the URL, the root state will be [Home, OnboardingModalNavigator (with the onboarding purpose screen)], then the REDIRECT guard will add another OnboardingModalNavigator, so we have 2 OnboardingModalNavigator on the stack, which we don't want.

+        // to them after the redirect screen is dismissed. Otherwise (fresh app with no stack),
+        // use the full redirect state which includes the base route (e.g., Home).
+        const routes = hasExistingFullScreenRoute && redirectRoute ? [...state.routes, redirectRoute] : redirectState.routes;


Preserve stack only for modal redirects

This condition preserves the existing stack for any redirect as long as a fullscreen route exists, but OnboardingGuard also issues non-modal redirects to ROUTES.HOME for completed users. In those cases the new behavior pushes Home on top of prior routes instead of replacing the stack, so back navigation can return users to pre-redirect screens that the guard intended to exit. The stack-preservation path should be gated to modal redirect targets only.

Useful? React with 👍 / 👎.

The failing checks are unrelated to this PR's changes.

test (job 1) failure: tests/unit/CardFeedUtilsTest.ts crashed with SIGSEGV (segmentation fault in the jest worker process). This is a flaky infrastructure issue, not a code problem. This PR only modifies RootStackRouter.ts and handleNavigationGuardRedirect.test.ts — the CardFeedUtilsTest is completely unrelated.

checklist failure: This is the PR Reviewer Checklist, which is expected to fail until a reviewer completes it.

Sorry, creating ad-hoc builds is outside my capabilities. You can trigger an ad-hoc build manually through the GitHub Actions workflow or by asking someone with access to the build pipeline.

bernhardoj · 2026-04-07T09:11:16Z

@MelvinBot let's update the code from line 97 to 116 with this code:

const isModalRedirect = redirectState.routes.some((route) => isModalGuardRedirectTarget(route.name));

let resetRoutes: typeof redirectState.routes = redirectState.routes;
if (isModalRedirect) {
    const redirectRoute = redirectState.routes.at(-1);
    const existingFullScreenRoute = state.routes.find((route) => isFullScreenName(route.name));
    // When the current stack already has a fullscreen route (e.g., a deep-linked report),
    // append only the redirect target on top of the existing routes so the user returns
    // to them after the redirect screen is dismissed. Otherwise (fresh app with no stack),
    // use the full redirect state which includes the base route (e.g., Home).
    resetRoutes = existingFullScreenRoute && redirectRoute ? [existingFullScreenRoute, redirectRoute] as typeof redirectState.routes : redirectState.routes;
}

const resetAction = CommonActions.reset({
    index: resetRoutes.length - 1,
    routes: resetRoutes,
} as PartialState<NavigationState>);

Then, please add this right above the handleNavigationGuards function.

const MODAL_GUARD_REDIRECT_TARGETS = new Set<string>([NAVIGATORS.ONBOARDING_MODAL_NAVIGATOR, NAVIGATORS.MIGRATED_USER_MODAL_NAVIGATOR]);

function isModalGuardRedirectTarget(name: string) {
    return MODAL_GUARD_REDIRECT_TARGETS.has(name);
}

MelvinBot · 2026-04-07T09:13:50Z

Done! I've applied both changes:

Added MODAL_GUARD_REDIRECT_TARGETS set and isModalGuardRedirectTarget helper above handleNavigationGuards
Updated the redirect logic (lines 97-116) to use isModalRedirect check — only preserving existing routes for modal guard redirect targets, and using find instead of some to get the actual existing fullscreen route

MelvinBot · 2026-04-07T09:29:09Z

Updated the unit test to match the new modal-only redirect preservation logic:

Replaced the "should not duplicate the redirect target" test (which tested the removed duplicate-detection check) with a new test: "should use the full redirect state for non-modal redirects even when fullscreen routes exist" — verifies that non-modal redirects (e.g., to SettingsSplitNavigator) use the full redirect state without preserving existing routes.
All 5 tests pass.

MelvinBot · 2026-04-07T09:30:39Z

Fixed the failing check: the handleNavigationGuards function in RootStackRouter.ts was creating a duplicate redirect route when the redirect target was already the focused route. Added an early return that skips the redirect when redirectTarget.name === focusedRoute.name, returning the current state unchanged.

Note: the remote branch also had a commit that replaced the original failing test with a different test case. Both changes have been merged.

bernhardoj · 2026-04-07T09:32:00Z

@FitseTLT I think it's not possible to cover all cases with a generic solution, so I borrowed some code from #86856 to focus only on the modal guard.

I think the reason #86258 can happen is that we append the existing routes with the onboarding navigator, and somehow, there is another modal screen with the Expensify title logo behind the onboarding navigator.
[Home, Unidentified modal screen, OnboardingModalNavigator]

Not sure why it could happen, but it's not happening anymore, and to prevent that from happening in the future, I decided to not append the existing route, but rather, conditionally put either Home or the existing full-screen route as the first route.
[Home/existing full screen route, OnboardingModalNavigator]

(what's left to fix is #86390 (comment))

Preserve the active fullscreen route for modal redirects

Using state.routes.find(...) here preserves the first fullscreen route in the stack, not the currently active one. This stack can contain multiple fullscreen routes (e.g., via handlePushFullscreenAction), so when a guard redirects to onboarding/migrated-user modal, the reset may become [oldFullscreen, modal] and dismissing the modal drops users onto an older screen instead of the screen they were on. Pick the last fullscreen route (the route directly under the modal) when building resetRoutes.

Useful? React with 👍 / 👎.

Yes this is correct @bernhardoj

@MelvinBot please fix this

Fixed — changed state.routes.find(...) to state.routes.findLast(...) so the most recently active fullscreen route is preserved instead of the first one in the stack.

FitseTLT · 2026-04-09T16:04:48Z

-    } else {
-        // Navigate to home to trigger guard evaluation
-        Navigation.navigate(ROUTES.HOME);


This is to fix what I wrote here: #86390 (comment)

(I asked if it safe to remove it here)

But the comment above the code says:

// Navigate to home to trigger guard evaluation

So our guard code change will handle it. NO?

That's for test drive modal guard, which doesn't exist anymore.

I don't understand how the problem you explained here relates with the scope of this pr. Is there any specific circumstance that this code makes the expected result of this pr fail?

Yes, the 6th step

Verify that after onboarding, you land on the deep-linked report room instead of the home page

But without this change I was able to land on the report. Are u saying for specific onboarding flow? For instance, the manage teams flow landed on the admin's room but I thought that was expected.

Can you test choosing Something else and complete the onboarding?

I couldn't test because of a new bug on main here

When multiple fullscreen routes exist in the stack, find() picks the first one which may be stale. Using findLast() preserves the most recently active fullscreen route so dismissing the redirect modal returns users to the correct screen.
