Proposal

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

Deleted Expense that was edited appears when user goes offline

What is the root cause of that problem?

The reason for this issue is that reportAction.pendingAction is not updated when the DeleteMoneyRequest command is called. As a result, reportAction.pendingAction remains delete after the command is executed. This causes the condition ReportActionsUtils.shouldReportActionBeVisible(reportAction, reportAction.reportActionID) to return true, and since isOffline is also true, the issue occurs

App/src/pages/home/report/ReportActionsList.tsx

Lines 194 to 199 in 9160fa5

	(reportAction) =>
	(isOffline ||
	ReportActionsUtils.isDeletedParentAction(reportAction) ||
	reportAction.pendingAction !== CONST.RED_BRICK_ROAD_PENDING_ACTION.DELETE ||
	reportAction.errors) &&
	ReportActionsUtils.shouldReportActionBeVisible(reportAction, reportAction.reportActionID),

The reason DeleteMoneyRequest did not update pendingAction is because we called the UpdateMoneyRequestDate command to update the date, and it returned a lastUpdateID greater than DeleteMoneyRequest.

App/src/libs/Middleware/SaveResponseInOnyx.ts

Line 33 in 539327d

if (requestsToIgnoreLastUpdateID.includes(request.command) || !OnyxUpdates.doesClientNeedToBeUpdated(Number(response?.previousUpdateID ?? 0))) {

The warning I mentioned for that.

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

We need the backend to update lastUpdateID for DeleteMoneyRequest because we send clientUpdateID to the API, but the response contains a different value, as shown in the image below:

send clientUpdateID: 1973749768

and reponse previousUpdateID: 1973749978 that should be previousUpdateID: 1973749769 and lastUpdateID: 1973749980

or
If we don't want to update the backend, then we should add the command DELETE_MONEY_REQUEST to the ignore list, something like this:

// ./src/libs/Middleware/SaveResponseInOnyx.ts#L8
const requestsToIgnoreLastUpdateID: string[] = [
    WRITE_COMMANDS.OPEN_APP,
+   WRITE_COMMANDS.DELETE_MONEY_REQUEST,
     ...
];

@aimane-chnaif 👀 on @huult 's proposal above plz

[aimane-chnaif]

@huult thanks for the proposal.

The reason for this issue is that reportAction.pendingAction is not updated when the DeleteMoneyRequest command is called.

This doesn't make sense to me. We're setting pendingAction to null upon DeleteMoneyRequest api success:

App/src/libs/actions/IOU.ts

Lines 5944 to 5953 in a99cf94

	{
	onyxMethod: Onyx.METHOD.MERGE,
	key: `${ONYXKEYS.COLLECTION.REPORT_ACTIONS}${chatReport?.reportID}`,
	value: {
	[reportPreviewAction?.reportActionID ?? '-1']: {
	pendingAction: null,
	errors: null,
	},
	},
	},

[aimane-chnaif]

I noticed that this bug only happens when edit date field. Not happening on other fields like description.
So I don't think the bug is related to lastUpdateID for DeleteMoneyRequest.

[huult]

The reason DeleteMoneyRequest did not update pendingAction is because we called the UpdateMoneyRequestDate command to update the date, and it returned a lastUpdateID greater than DeleteMoneyRequest.

Can you check this command? The API responds, but the data is not stored locally due to the reason I mentioned. You can add a log above this condition, and you will see.

[aimane-chnaif]

@huult please also check #49329 (comment).
Please explain why this happens only on date field.

[aimane-chnaif]

The root cause is quite similar to #44114 (comment)
Possibly fix in BE 🎀👀🎀

📣 It's been a week! Do we have any satisfactory proposals yet? Do we need to adjust the bounty for this issue? 💸

[mallenexpensify]

@jasperhuangg , can you confirm if you think this issue is BE?
You don't need to leave yourself assigned.

[huult]

@jasperhuangg , When does the expense delete successfully on the server? I waited for 1 minute and disconnected the network, but the issue still occurred.
If we know when the deletion is successful, I suggest keeping the data, including the amount, until it is deleted on the server and then deleting it.

[jasperhuangg]

@huult, I see; sorry for the misunderstanding. In that case, your alternative approach of adding the command to the ignore list should work! If the user intends to delete the money request, it doesn't seem like we need to wait for any requests to update fields in the money request.
