Proposal

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

Clicking the back button on the Merchant page for an expense takes to a blank page with just the LHN

What is the root cause of that problem?

We are not passing the onBackButtonPress prop to the HeaderWithBackButton component.

App/src/pages/EditRequestMerchantPage.js

Line 50 in ccad061

<HeaderWithBackButton title={translate('common.merchant')} />

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

Pass the prop with Navigation.dismissModal()
<HeaderWithBackButton onBackButtonPress={() => Navigation.dismissModal()} title={translate('common.merchant')} />

What alternative solutions did you explore? (Optional)

Proposal

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

Clicking the back button on the Merchant page for an expense takes to a blank page with just the LHN

What is the root cause of that problem?

We are missing the back button logic in EditRequestMerchantPage

App/src/pages/EditRequestMerchantPage.js

Line 50 in ccad061

<HeaderWithBackButton title={translate('common.merchant')} />

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

We shoud pass onBackButtonPress={Navigation.goBack} as the prop, like we do in similar pages.

Maybe related to: #35626

[trjExpensify]

@adamgrzybowski is going to sense check whether his solution on the main issue addressing goBack bugs will fix this. Let's hold on making a PR until then!

[adamgrzybowski]

@trjExpensify should be fixed by #36050

[hayata-suenaga]

The issue is tracked in #35626. Closing this in favor of that one 🙇
