The Rate field is not on staging for me in my tom@trj.chat account, because it's a feature behind the p2pDistanceRequests beta and that account isn't on the beta.

So I think this can be demoted as a deploy blocker.

[trjExpensify]

Testing on my expensify.com account which is on the beta, I'm getting this when the UpdateMoneyRequestDistanceRate command is called:

jsonCode: 501, message: "501 Invalid tax percentage", onyxData: [], requestID: "8af762156c4bbefd-LHR"}
"501 Invalid tax percentage"
8af762156c4bbefd-LHR

Internal logs for that requestID are here.

Could not calculate taxAmount, taxPercentage: , and amount: 0

Throwing exception with message: '501 Invalid tax percentage' from auth/lib/Transaction.cpp:3065

That's here in Auth.

@MonilBhavsar any insight as you added this in the blame? 🤔 (CC: @nkdengineer as well for context on building this feature a few months ago!)

[MonilBhavsar]

I was assigned couple of server errors too. Something looks off with the command. Looking into it

[trjExpensify]

Amazing! Do you agree this isn't an /app blocker though, given you can't access this Rate field on the expense to change if you aren't on the p2pDistanceRequests beta?

[MonilBhavsar]

agree, shouldn't be an app blocker, neither web. The logic lies in Auth.

But I wonder, in this case if user does not select tax rate and tax claimable percentage. Should we fallback to workspace default tax percentage?

[MonilBhavsar]

But wait. Why this created as blocker though 🤔

[mountiny]

@cristipaval @MonilBhavsar I agree this does not have to be a blocker cc @neil-marcellini as its related to the p2p distance

Feel free to remove the labels

[trjExpensify]

But wait. Why this created as blocker though 🤔

You hit this error if you change the Rate field on the distance expense, under the conditions in the steps in the OP.

But I wonder, in this case if user does not select tax rate and tax claimable percentage. Should we fallback to workspace default tax percentage?

No, I don't think we do that on OldDot do we? Just the output is $0.00. Let me check.

[trjExpensify]

Yeah, we just leave the tax amount at $0.00 and uneditable - we don't default to the workspace default tax rate or anything as far as I can tell.

[MonilBhavsar]

Okay, thanks for looking! 🙌

Here, we need to skip calculating tax percentage if taxCode is empty(not set by user), and add automated tests https://github.com/Expensify/Auth/blob/c15ed2282c02386eb3d2239ff33263994c4ec798/auth/command/UpdateMoneyRequestDistanceRate.cpp#L90

I'm prioritising fire cleanup task currently, so not picking up

[MonilBhavsar]

I'm working on https://github.com/Expensify/Expensify/issues/418428, and that should fix this issue

[melvin-bot[bot]]

@cristipaval, @Christinadobrzyn Huh... This is 4 days overdue. Who can take care of this?

[Christinadobrzyn]

Thanks @MonilBhavsar! I'll add a hold label to retest after https://github.com/Expensify/Expensify/issues/418428 is deployed

[cristipaval]

I'm handing this over to you, @MonilBhavsar, as I get closer to my parental leave. Thanks for fixing 🙏
