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

Self DM appears twice in Recents section after deleting two empty reports.

What is the root cause of that problem?

We have the cache for the self DM report ID here

App/src/libs/ReportUtils.ts

Lines 1208 to 1212 in ae4cd7c

	let cachedSelfDMReportID: OnyxEntry<string>;
	Onyx.connectWithoutView({
	key: ONYXKEYS.SELF_DM_REPORT_ID,
	callback: (value) => (cachedSelfDMReportID = value),
	});

App/src/libs/ReportUtils.ts

Lines 1876 to 1879 in ae4cd7c

	function findSelfDMReportID(): string | undefined {
	if (cachedSelfDMReportID) {
	return cachedSelfDMReportID;
	}

The first time we delete a report, we create the selfDM report onyx data here

App/src/libs/actions/Report.ts

Lines 4965 to 4973 in ae4cd7c

	let selfDMReportID = findSelfDMReportID();
	let selfDMReport = allReports?.[`${ONYXKEYS.COLLECTION.REPORT}${selfDMReportID}`];
	let createdAction: ReportAction;
	let selfDMParameters: SelfDMParameters = {};
	if (!selfDMReport) {
	const currentTime = DateUtils.getDBTime();
	selfDMReport = buildOptimisticSelfDMReport(currentTime);
	selfDMReportID = selfDMReport.reportID;

But we not update the ONYXKEYS.SELF_DM_REPORT_ID => On the second deletion attempt, selfDMReport was still undefined=> We create another new selfDM report.

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

We should change ONYXKEYS.SELF_DM_REPORT_ID when we create the self DM report.

            {
                onyxMethod: Onyx.METHOD.MERGE,
                key: `${ONYXKEYS.SELF_DM_REPORT_ID}`,
                value: selfDMReportID,
            },

App/src/libs/actions/Report.ts

Line 4976 in ae4cd7c

optimisticData.push(

Alternatively, we could add a flag to avoid using the cache in this case.

    function findSelfDMReportID(shouldUseCache: boolean = true): string | undefined {
        if (shouldUseCache && cachedSelfDMReportID) {
            return cachedSelfDMReportID;
        }

App/src/libs/ReportUtils.ts

Lines 1876 to 1879 in ae4cd7c

	function findSelfDMReportID(): string | undefined {
	if (cachedSelfDMReportID) {
	return cachedSelfDMReportID;
	}

Expense - Self DM appears twice in Recents section after deleting two empty reports

What is the root cause of that problem?

When deleting multiple empty reports quickly, each deletion would call deleteAppReport, which would check for an existing Self DM using findSelfDMReportID(). When the first deletion created a new Self DM, it was only added to the optimistic data, not to the cached ONYXKEYS.SELF_DM_REPORT_ID. So when the second deletion happened immediately after, findSelfDMReportID() still returned undefined because:

• The cache cachedSelfDMReportID was not updated
• The first Self DM was in optimistic data, not in allReports yet

This caused two separate Self DM reports to be created.

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

We should add an Onyx.merge call to update ONYXKEYS.SELF_DM_REPORT_ID right after creating a new Self DM report in deleteAppReport

if (!selfDMReport) {
    const currentTime = DateUtils.getDBTime();
    selfDMReport = buildOptimisticSelfDMReport(currentTime);
    selfDMReportID = selfDMReport.reportID;
    createdAction = buildOptimisticCreatedReportAction(currentUserEmailParam ?? '', currentTime);
    selfDMParameters = {reportID: selfDMReport.reportID, createdReportActionID: createdAction.reportActionID};
    
    // Update the cached Self DM report ID to prevent duplicate Self DM creation
    Onyx.merge(ONYXKEYS.SELF_DM_REPORT_ID, selfDMReport.reportID);

here

App/src/libs/actions/Report.ts

Lines 4971 to 4976 in 8d19e95

	if (!selfDMReport) {
	const currentTime = DateUtils.getDBTime();
	selfDMReport = buildOptimisticSelfDMReport(currentTime);
	selfDMReportID = selfDMReport.reportID;
	createdAction = buildOptimisticCreatedReportAction(currentUserEmailParam ?? '', currentTime);
	selfDMParameters = {reportID: selfDMReport.reportID, createdReportActionID: createdAction.reportActionID};

Expense - Self DM appears twice in Recents section after deleting two empty reports

What is the root cause of that problem?

When users delete the report, we’ll find the selfDMReportID and selfDMReport

App/src/libs/actions/Report.ts

Lines 4965 to 4966 in ae4cd7c

	let selfDMReportID = findSelfDMReportID();
	let selfDMReport = allReports?.[`${ONYXKEYS.COLLECTION.REPORT}${selfDMReportID}`];

selfDMReportID will be read from selfDMReportID Onyx data and it always has value, but for the new account, selfDMReport is undefined. If it’s undefined, we’ll create the new one and send to BE with reportID and createdReportActionID

After delete the first report, we already create the new selfDMReport, but we didn’t pass the selfDMReportID to buildOptimisticCreatedReportAction so it’ll generate the new report with different reportID from selfDMReportID

App/src/libs/actions/Report.ts

Line 4972 in ae4cd7c

selfDMReport = buildOptimisticSelfDMReport(currentTime);

That why selfDMReport is still undefined after deleting the first one.

We shouldn’t generate the new selfDMReportID because BE will throw the error when we try to send the message on that report

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

Update this line

App/src/libs/actions/Report.ts

Line 4972 in ae4cd7c

selfDMReport = buildOptimisticSelfDMReport(currentTime);

To

       selfDMReport = buildOptimisticSelfDMReport(currentTime, selfDMReportID);

Dupe self dm report shows in start chat page after deleting 2 empty reports.

What is the root cause of that problem?

When we delete a report, we will create an optimistic self dm report if it doesn't exist yet on the FE.

App/src/libs/actions/Report.ts

Lines 4965 to 4986 in 1d1ea3d

	let selfDMReportID = findSelfDMReportID();
	let selfDMReport = allReports?.[`${ONYXKEYS.COLLECTION.REPORT}${selfDMReportID}`];
	let createdAction: ReportAction;
	let selfDMParameters: SelfDMParameters = {};
	if (!selfDMReport) {
	const currentTime = DateUtils.getDBTime();
	selfDMReport = buildOptimisticSelfDMReport(currentTime);
	selfDMReportID = selfDMReport.reportID;
	createdAction = buildOptimisticCreatedReportAction(currentUserEmailParam ?? '', currentTime);
	selfDMParameters = {reportID: selfDMReport.reportID, createdReportActionID: createdAction.reportActionID};
	optimisticData.push(
	{
	onyxMethod: Onyx.METHOD.SET,
	key: `${ONYXKEYS.COLLECTION.REPORT}${selfDMReport.reportID}`,
	value: {
	...selfDMReport,
	pendingFields: {
	createChat: CONST.RED_BRICK_ROAD_PENDING_ACTION.ADD,
	},
	},
	},

We check whether it exists by getting the report based on the ID from findSelfDMReportID, which returns the ID from selfDMReportID onyx key. However, every user already has a self dm report on the BE. So, when we delete the empty report twice, we create 2 optimistic reports because each optimistic report has a different reportID.

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

First, we need to pass the self DM report ID from findSelfDMReportID when creating the optimistic report so the optimistic report is created with the same reportID we have on the BE.

selfDMReport = buildOptimisticSelfDMReport(currentTime, selfDMReportID);

Next, we need to remove the optimistic created action, otherwise we will have 2 created actions on the report. We will also remove the selfDMParameters as it's unused now. The end result will look like this:

let selfDMReportID = findSelfDMReportID();
let selfDMReport = allReports?.[`${ONYXKEYS.COLLECTION.REPORT}${selfDMReportID}`];

if (!selfDMReport) {
    const currentTime = DateUtils.getDBTime();
    selfDMReport = buildOptimisticSelfDMReport(currentTime, selfDMReportID);
    selfDMReportID = selfDMReport.reportID;
    optimisticData.push(
        {
            onyxMethod: Onyx.METHOD.SET,
            key: `${ONYXKEYS.COLLECTION.REPORT}${selfDMReport.reportID}`,
            value: selfDMReport,
        },
        {
            onyxMethod: Onyx.METHOD.MERGE,
            key: `${ONYXKEYS.COLLECTION.REPORT_METADATA}${selfDMReport.reportID}`,
            value: {
                isOptimisticReport: false,
            },
        },
    );
}

NOTE: we can optionally only create the self DM report if the report that we delete contains transaction because when it's an empty report, the DeleteAppReport API doesn't return the self DM report data as the response.
