Action Performed:

Precondition:

1. Go to staging.new.expensify.com
2. Go to workspace chat.
3. Open the expense report that has card and cash transactions from above.
4. Open the CASH expense.
5. Click More > Merge.
6. Select the CARD transaction (same details as the cash expense).
7. Click Continue.

Expected Result:

Since the card and cash transactions share the same details, confirmation page will open directly.

When the card and cash transactions share the same details, Select details page is empty.

We already checked if there is any merge conflict fields here

App/src/pages/TransactionMerge/MergeTransactionsListContent.tsx

Lines 141 to 147 in b12e658

	const {conflictFields, mergeableData} = getMergeableDataAndConflictFields(targetTransaction, sourceTransaction);
	if (!conflictFields.length) {
	// If there are no conflict fields, we should set mergeable data and navigate to the confirmation page
	setMergeTransactionKey(transactionID, mergeableData);
	Navigation.navigate(ROUTES.MERGE_TRANSACTION_CONFIRMATION_PAGE.getRoute(transactionID, Navigation.getActiveRoute()));
	return;
	}

However, we put incorrect targetTransaction and sourceTransaction. When merging a cash expense with a card transaction, we auto-select the card transaction as target. I fixed this issue in this commit 86fc7b5
