SAP ESS WORK FLOW ERROR || LEAVE REQUESTOR EMAIL IS EMPTY WORKFLOW IS STOPPED.

Hi Team,

I am seeking your assistance to check what might be the reason why my manager can't approve the leave request because of the error message below. I confirmed that the email address of the employee and manager are active, It's weird why it's showing this kind of error message even though there's no issue on the master data.

I hope you can help me on this.

Thank you in advance.
