We think that this bug might be related to #vip-vsb

[pecanoro]

I can reproduce but if it's not coming from the back-end, I am wondering if we changed the API request in some PR, looking!

[pecanoro]

Oh, on production we call TrackExpense and we call CreateDistanceRequest on staging

[pecanoro]

It's coming from this PR: https://github.com/Expensify/App/pull/42302

[pecanoro]

I am going to open it for proposals since everyone involved in the original PR is not online and if we don't get any, I will revert the original PR.

Proposal

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

App throws error when submitting track distance expense - There is a previously existing chat between these users.

What is the root cause of that problem?

In the PR https://github.com/Expensify/App/pull/42302, we mistakenly moved the createDistanceRequest(iouType == condition to the top (this change https://github.com/Expensify/App/pull/42302/files#diff-5e5fc302dd5db871d26e30f810bc0606beccb7f50ae6ed6535cd93aaee98c280), causing it to be evaluated first and not trackExpense, so it calls CreateDistanceRequest in track distance expense case instead of TrackExpense

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

Move this block back to its correct location before the PR which is here https://github.com/Expensify/App/blob/0926267c22e50e68b52c055dacc3af775235ccd4/src/pages/iou/request/step/IOURequestStepConfirmation.tsx#L505

What alternative solutions did you explore? (Optional)

Update this block to

if (iouType !== CONST.IOU.TYPE.TRACK && isDistanceRequest && !isMovingTransactionFromTrackExpense) {
                createDistanceRequest(iouType === CONST.IOU.TYPE.SPLIT ? splitParticipants : selectedParticipants, trimmedComment);
                return;
            }

So it will only createDistanceRequest if it's not a track expense, we can extend the iouType check for other iou types if needed (if there're other IOU types that should not call createDistanceRequest but uses its own method, like track expense)

[dominictb]

Proposal updated to add alternative approach

[jjcoffee]

Hmm, I don't think we can just move createDistanceRequest back down as that would most likely cause a regression from https://github.com/Expensify/App/pull/42302 since we'd call IOU.splitBill first and return early instead of creating the distance request for splitting.

~I wonder if we also need to handle~ !isMovingTransactionFromTrackExpense covers the other conditions that result in calling trackExpense:

https://github.com/Expensify/App/blob/717d344a38bb04265d219a5143d6ab0dd70596ed/src/pages/iou/request/step/IOURequestStepConfirmation.tsx#L446

[jjcoffee]

Having investigated further, it looks like @dominictb's alternative solution is the way to go here.
