We think that this bug might be related to #wave-collect - Release 1

@srikarparsi FYI I haven't added the External label as I wasn't 100% sure about this issue. Please take a look and add the label if you agree it's a bug and can be handled by external contributors

Regression from #39059, you take the value of default tax rate as default external ID:

App/src/pages/iou/request/step/IOURequestStepTaxRatePage.tsx

Line 49 in dd30d13

const defaultTaxKey = taxRates?.defaultExternalID;

But, in api response the default external ID is:

And the when we select the selected tax rate:

App/src/pages/iou/request/step/IOURequestStepTaxRatePage.tsx

Line 51 in dd30d13

const selectedTaxRate = transaction?.taxRate?.keyForList || defaultTaxKey;

We check for transaction?.taxRate?.keyForList if it exists, but the api response doesn't have such field IMO.

We should instead do:

const selectedTaxRate = TransactionUtils.getDefaultTaxName(taxRates, transaction);

@SzymczakJ @jjcoffee are you able to take a look at this?

[srikarparsi]

Working on testing if reverting the TS migration fixes the issue. VM is having some problems so taking a bit.

[srikarparsi]

Able to reproduce on latest main:

Trying to roll back TS migration and test again.

[srikarparsi]

Hey @luacmartins and @MonilBhavsar, saw that you demoted this tax issue since it's coming from a new feature. This one seems very related as the code that's causing the discrepancy is selectedTaxRate. Should we demote this one as well?

I'm currently working on trying to revert the TS Migration PR in case it's related to that but am not able to do it on Web so trying to do it locally. But wanted to ask in the meantime.

[srikarparsi]

Figured out a fix here

[srikarparsi]

Checked to see if any C+ is able to review the fix

[srikarparsi]

Still looking at this, I've been having VM problems so it's taking a little longer. Thought I had resolved them but still occurring.

[srikarparsi]

I narrowed it down to this sections variable. When printed, it has id_TAX_EXEMPT as it's own sections and the remaining taxes in a different section.

I also found that when you select a different tax value and then the default tax exempt one, the bug no longer exists. So maybe it's something to do with a different id?

[srikarparsi]

The bug also doesn't exist for less than 8 tax rates because of this block here

[teneeto]

Hi, I'm Eto from Callstack - expert contributor group - and I would like to take care of this issue.

[teneeto]

This issue is currently handled in this PR: #39723

[srikarparsi]

Ah cool, see that you had a similar fix

const moneyRequestSelectedTaxRate = transaction?.taxRate?.keyForList || (taxRates && TransactionUtils.getDefaultTaxName(taxRates));

Assigning you to the issue

[MonilBhavsar]

Demoting this issue from blocker, as we need to have atleast 8 tax options and it's a specific case.
