Hire an Employee Approval Rules, management hierarchy error

Hello,

we are configuring an approval rule for the Hire an Employee transaction and we are facing issues when trying to route an FYI notification to the worker’s proposed line manager. Every configuration we are using gives back an errore or redirects to the second level manager.

Requirement:
At the end of the Hire transaction, we need to send an FYI (Information Only) notification to the manager selected in the hire.

This is the configuration we are trying to use:

This configuration gives back an error.

Is there a way to configure the approval rule following the requirement?

Thank you!
