Proposal

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

Search - App crashes when clicking on search icon while app is loading

What is the root cause of that problem?

The personalDetailsForParticipants is null/undefined immediately after clearing cache so it cannot be converted to object here

App/src/components/Search/SearchRouter/SearchRouter.tsx

Line 126 in 09f6db7

Object.values(personalDetailsForParticipants)

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

We should use

            Object.values(personalDetailsForParticipants ?? {})

or we can use a backup empty object here like this

App/src/pages/RoomMembersPage.tsx

Line 59 in 09f6db7

const personalDetails = usePersonalDetails() || CONST.EMPTY_OBJECT;

What alternative solutions did you explore? (Optional)

App crashes when clicking on search icon while app is loading

What is the root cause of that problem?

After we clear the cache, personalDetailsForParticipants become undefined

App/src/components/Search/SearchRouter/SearchRouter.tsx

Line 122 in a54f913

const personalDetailsForParticipants = usePersonalDetails();

Then the app crashes here when we open the search page

App/src/components/Search/SearchRouter/SearchRouter.tsx

Lines 126 to 129 in a54f913

	Object.values(personalDetailsForParticipants)
	.filter((details): details is NonNullable<PersonalDetails> => !!(details && details?.login))
	.map((details) => ({
	name: details.displayName ?? Str.removeSMSDomain(details.login ?? ''),

But if the personalDetailsForParticipants to be undefined why no ts error when we use Object.values(personalDetailsForParticipants) here?

App/src/components/Search/SearchRouter/SearchRouter.tsx

Lines 126 to 129 in a54f913

	Object.values(personalDetailsForParticipants)
	.filter((details): details is NonNullable<PersonalDetails> => !!(details && details?.login))
	.map((details) => ({
	name: details.displayName ?? Str.removeSMSDomain(details.login ?? ''),

The problem from here, usePersonalDetails is a hook context that is created from createOnyxContext

App/src/components/OnyxProvider.tsx

Line 9 in a54f913

const [, PersonalDetailsProvider, , usePersonalDetails] = createOnyxContext(ONYXKEYS.PERSONAL_DETAILS_LIST);

The return value of this hook is cast as NonNullable<OnyxValue<TOnyxKey>>, then there's no waring when we use like this Object.values(personalDetailsForParticipants)

App/src/components/createOnyxContext.tsx

Line 36 in a54f913

() => NonNullable<OnyxValue<TOnyxKey>>,

App/src/components/createOnyxContext.tsx

Line 90 in a54f913

return value as NonNullable<OnyxValue<TOnyxKey>>;

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

To avoid the same case can happen in the feature, we can return the type here as OnyxValue<TOnyxKey> here

App/src/components/createOnyxContext.tsx

Line 36 in a54f913

() => NonNullable<OnyxValue<TOnyxKey>>,

and remove the cast type here

App/src/components/createOnyxContext.tsx

Line 90 in a54f913

return value as NonNullable<OnyxValue<TOnyxKey>>;

After that, we can see all waring places via ts error or lint error that possible cause the app crashes when we use the value from the createOnyxContext hook and fix all places.

or if the value here is undefined, we can return a non null value based on the type of OnyxValue<TOnyxKey>. For example, return empty object if this type is an object, return empty array if the type is array,...

App/src/components/createOnyxContext.tsx

Line 90 in a54f913

return value as NonNullable<OnyxValue<TOnyxKey>>;
