Proposal

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

On deleting parent message,text "Deleted message" is not shown

What is the root cause of that problem?

We are using getGroupChatName to get the report name here

App/src/pages/ReportDetailsPage.tsx

Lines 244 to 245 in d4d5a25

	const reportName = ReportUtils.isDeprecatedGroupDM(report) || isGroupChat ? ReportUtils.getGroupChatName(undefined, false, report) : ReportUtils.getReportName(report);

Because isGroupChat will be true for chat threads opened inside group chats

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

isGroupChat is not enough and we also need to check that it is not chat thread

    const reportName = ReportUtils.isDeprecatedGroupDM(report) || (isGroupChat && !isChatThread) ? ReportUtils.getGroupChatName(undefined, false, report) : ReportUtils.getReportName(report);

or

    const reportName = ReportUtils.isDeprecatedGroupDM(report) || (isGroupChat && !isThread) ? ReportUtils.getGroupChatName(undefined, false, report) : ReportUtils.getReportName(report);

same fix should be applied here too if we are not going to update isGroupChat as suggested in my alternative approach (which fix the problem from the root cause)

App/src/components/LHNOptionsList/OptionRowLHN.tsx

Line 134 in 578006f

const fullTitle = isGroupChat ? ReportUtils.getGroupChatName(undefined, false, report) : optionItem.text;

What alternative solutions did you explore? (Optional)

As chat threads with group chat as their parent report also have chatType as group; everywhere we are using isGroupChat in the app, we are wrongly including these chat threads. so the current code to determine isGroupChat is not correct and the one we should fix it from the root cause and avoid similar problems in the whole code base

App/src/libs/ReportUtils.ts

Lines 1140 to 1141 in d4d5a25

	function isGroupChat(report: OnyxEntry<Report> | Partial<Report>): boolean {
	return getChatType(report) === CONST.REPORT.CHAT_TYPE.GROUP;

so should be changed to

    return getChatType(report) === CONST.REPORT.CHAT_TYPE.GROUP && !isThread(report);

Proposal

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

If a thread is created on a group chat and the thread is deleted with a message, the report detail page shows the thread name instead of [Deleted message]

What is the root cause of that problem?

If the report is a group chat, then we use getGroupChatName to get the name. A thread always inherits its parent chat type, so a thread in a group chat is a group chat.

App/src/pages/ReportDetailsPage.tsx

Line 244 in 578006f

const reportName = ReportUtils.isDeprecatedGroupDM(report) || isGroupChat ? ReportUtils.getGroupChatName(undefined, false, report) : ReportUtils.getReportName(report);

getGroupChatName itself returns the reportName of a report if found and a thread reportName is the thread parent message.

App/src/libs/ReportUtils.ts

Lines 2140 to 2144 in 578006f

	function getGroupChatName(participants?: SelectedParticipant[], shouldApplyLimit = false, report?: OnyxEntry<Report>): string | undefined {
	// If we have a report always try to get the name from the report.
	if (report?.reportName) {
	return report.reportName;
	}

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

Remove the group chat check and just use ReportUtils.getReportName. ReportUtils.getReportName already handles the group chat case.

App/src/libs/ReportUtils.ts

Lines 3736 to 3738 in 578006f

	if (isGroupChat(report)) {
	return getGroupChatName(undefined, true, report) ?? '';
	}

We need to fix in OptionRowLHN too by removing the group chat check.

App/src/components/LHNOptionsList/OptionRowLHN.tsx

Line 134 in 578006f

const fullTitle = isGroupChat ? ReportUtils.getGroupChatName(undefined, false, report) : optionItem.text;
