Cannot process the corporate card expenses marked as personal expenses

There is an employee expense report which includes the corporate card transactions. Some of the transactions are marked as personal expenses when submitting the expense report.
Expense report is approved. However, when Process Expense Reimbursements and Cash Advances is submitted, the expense report is rejected.

Rejection Description - Financial option not defined

Expectation was to create a negative invoice to reimburse from the employee.

Can you help to find the missing configuration if any? I assume it is because there is no expense account since it is personal. Is there a configuration to default an account for these?
