This was found while testing here: https://github.com/Expensify/Auth/pull/11671#issuecomment-2248437345

Action Performed:

1. Open NewDot in an incognito window (fresh session with empty onyx)
2. Open the chrome dev console and run the snippet:
   mergecollectionsbug-snippet.txt
3. Go to the tab to see Onyx data and find the report report_7258727734156717

Expected Result:

The report report_7258727734156717 should be complete and contain:

{
    "chatType": "policyExpenseChat",
    "lastActorAccountID": 11039535,
    "lastMessageText": "",
    "lastReadTime": "2024-07-22 19:27:42.872",

This bug seems to be getting fixed by: Expensify/react-native-onyx#490, so I'll ask when we are planning to have that in the App

[aldo-expensify]

I tried to write a unit test to include in our test suit for this, but the unit test works just fine 😠:

 it.only('applies PUSHER Onyx updates correctly', () => {
        // When we apply the updates, then their values are updated correctly
        return Onyx.update(xxx) // these are the updates from the snippet in the GH issue body
            .then(() => getOnyxValue('report_7258727734156717'))
            .then((report) => {
                expect(report).toStrictEqual({
                        "chatType": "policyExpenseChat",
                        "lastActorAccountID": 11039535,
                        "lastMessageText": "",
                        "lastVisibleActionCreated": "2024-07-22 19:27:42.872",
                        "managerID": 0,
                        "notificationPreference": "always",
                        "ownerAccountID": 11039535,
                        "policyAvatar": "",
                        "policyID": "164FF81CBF695B8D",
                        "policyName": "ImTheAdmin ADMIN''s Workspace",
                        "reportID": "7258727734156717",
                        "reportName": "Chat Report",
                        "stateNum": 0,
                        "statusNum": 0,
                        "type": "chat",
                        "lastReadTime": "2024-07-22 19:27:42.872",
                });
            });
    });
});
