I have a scheduled flow which is set to run daily to send an email if a certain condition is met. This flow works as intended if I manually enter the email address into the flow as shown below.

However, my SharePoint list has an item owner field which is set as Person or Group. When I change the email recipient from the manually entered email address to the owner email the flow adds two additional 'For Each' steps and the email is not sent.

Can anyone advise where I am going wrong with this.
Thanks in advance
