Proposal

Please re-state the problem that we are trying to solve in this issue.

App crashes on pasting the public room URL again after navigating back

What is the root cause of that problem?

We're using getTopmostReportId even when the navigation is not ready, which make the state undefined.

Now the app will be crashed because the state is undefined and we are checking for state.routes.

What changes do you think we should make in order to solve the problem?

We can update the original getTopmostReportId function here with an early return

function getTopmostReportId(state) {
    if (!state) {
        return;
    }

or we can update getTopmostReportId inside Navigation.js to this.

const getTopmostReportId = (state = navigationRef.getState()) => {
   if (!navigationRef.isReady()) {
       return;
   }
  return  originalGetTopmostReportId(state);
};

@sonialiap

Hey there @sonialiap as discussed in slack I know this issue still has no external tag and might not become external but here is already draft PR that solves the issue, it might help you avoid additional work

Proposal

Please re-state the problem that we are trying to solve in this issue.

Web app crashes when user inputs again the URL after going back from sign in page

What is the root cause of that problem?

After opening the second time the React Navigation library returns an undefined state, which is sent to updateSavedNavigationStateAndLogRoute

What changes do you think we should make in order to solve the problem?

Instead of having guards in the children methods I recommend having the guard in the parent NavigationRoot.js:

const updateSavedNavigationStateAndLogRoute = (state) => {
        if (!state) {
            return
        }
        navigationStateRef.current = state;
        props.updateCurrentReportId(state);
        parseAndLogRoute(state);
    };

Video of the solution working:
Mobile Browser - 14_6_2023, 14_55_36.webm
New Recording - 14_6_2023, 14_54_41.webm

What alternative solutions did you explore? (Optional)

I began trying a guard in getTopmostReportId but diving into the origin of the issue it is better to use it in the parent in case any additional method is used in updateSavedNavigationStateAndLogRoute
We can also validate with Software Mansion and check if the behavior of receiving and undefined state from the library is correct.

Looks like something related to react-navigation may have been mentioned in this issue discussion.

As a reminder, please make sure that all proposals are not workarounds and that any and all attempt to fix the issue holistically have been made before proceeding with a solution. Proposals to change our DeprecatedCustomActions.js files should not be accepted.

Feel free to drop a note in #expensify-open-source with any questions.
