New Hire Approval Error when Approver is the Payroll Rep AOR

Summary:

We have a scenario where the new hire approvals are erroring out when the approver is set to Payroll Representative (AOR with Responsibility Scope - Payroll)

Content (please ensure you mask any confidential information):

We follow creating pending workers and then converting them into an employee process. The pending workers will be having the payroll added and while converting, the same payroll value will flow over to the employee record. We are expecting the workflow to route the approvals to the Payroll Representative based on the worker's payroll but the transaction is moving to an error state.

Is this expected functionality and is there a workaround to route the approvals to the Payroll Reps for the new hire workflow?
