Proposal

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

App crashes when leaving thread

What is the root cause of that problem?

in the following line report.notificationPreference is null so it throws an error when it tries to access the length.

App/src/pages/home/HeaderView.js

Line 145 in e7ef4bd

} else if ((isChatThread && props.report.notificationPreference.length) || isUserCreatedPolicyRoom || canLeaveRoom) {

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

this issue orginates because of the optimistic value we set when leaving a room:

App/src/libs/actions/Report.ts

Lines 2049 to 2058 in 41471e9

	value: {
	reportID,
	stateNum: CONST.REPORT.STATE_NUM.SUBMITTED,
	statusNum: CONST.REPORT.STATUS.CLOSED,
	chatType: report.chatType,
	parentReportID: report.parentReportID,
	parentReportActionID: report.parentReportActionID,
	policyID: report.policyID,
	type: report.type,
	},

here we dont add the notificationPreference

so we have two solutions

either to add notificationPreference as hidden:

     : {
                  onyxMethod: Onyx.METHOD.SET,
                  key: `${ONYXKEYS.COLLECTION.REPORT}${reportID}`,
                  value: {
                      reportID,
                      stateNum: CONST.REPORT.STATE_NUM.SUBMITTED,
                      statusNum: CONST.REPORT.STATUS.CLOSED,
                      chatType: report.chatType,
                      parentReportID: report.parentReportID,
                      parentReportActionID: report.parentReportActionID,
                      policyID: report.policyID,
                      type: report.type,
                      notificationPreference: CONST.REPORT.NOTIFICATION_PREFERENCE.HIDDEN,
                  },

or we add another condition that checks if thereport.notificationPreference exists first before accessing the length

I confirmed that this also happens on production. Not deploy blocker but it would be good to fix asap as it's "crash"
@abzokhattab's proposal looks good to me.

In addition, we can add fix some more optimistic data to be consistent with server.
For now, there's glitch. i.e. chat is archived optimistically and then restores back

@situchan sorry for my late, could you help to check my proposal?

Proposal

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

App crashes when leaving thread

What is the root cause of that problem?

When leaving the room we don't set notificationPreference in optimistic Data and we using SET method to update thread report to ONYX. It caused notificationPreference is lost in the chat report.
One more thing, after leaving the room, the App don't redirect to the parent report.

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

we need to add fully optimistic data to match the data from BE.

I think we should redirect to the parent report after the user leaving room. In here

App/src/libs/actions/Report.ts

Line 2117 in b950c1e

}

we should update like this

 if (isWorkspaceMemberLeavingWorkspaceRoom) {
        const participantAccountIDs = PersonalDetailsUtils.getAccountIDsByLogins([CONST.EMAIL.CONCIERGE]);
        const chat = ReportUtils.getChatByParticipants(participantAccountIDs);
        if (chat?.reportID) {
            Navigation.navigate(ROUTES.REPORT_WITH_ID.getRoute(chat.reportID));
        }
+ return
    }
+    if (report?.parentReportID) {
+      Navigation.navigate(ROUTES.REPORT_WITH_ID.getRoute(report.parentReportID));
+  }

What alternative solutions did you explore? (Optional)

NA

I confirmed that this also happens on production.

I was unable to reproduce this on v1.4.11-25.

[situchan]

@Julesssss constantly reproducible on production
Because of this crash, not able to test #33010. I think 2 issues can be fixed together in one PR.

Screen.Recording.2023-12-14.at.4.29.46.PM.mov

[situchan]

Please test on public room

[Julesssss]

I can't reproduce this in a 1:1 chat on web or Android. But yeah I can reproduce in a public room.

The problem is that a new regression has been introduced for the 1:1 chats, so as much as I'd like to drop this from being a blocker, we'll have to fix it asap.

[blazejkustra]

Turns out this PR also fixes crashes when leaving threads. cc @Julesssss

[situchan]

yeah, confirmed PR fixes both issues.
I think notificationPreference: CONST.REPORT.NOTIFICATION_PREFERENCE.HIDDEN, should be applied to !isWorkspaceMemberLeavingWorkspaceRoom as well

[Julesssss]

This was CP'd to staging and released. Removing the label.
