I have a requirement to populate a person column with the manager of the person selected in another person column
In the requestor column I have the following properties
Items:
Choices([@AUGBE_TEST].Requestor)
DefaultSelectedItems:
If(
Form1.Mode = FormMode.New,
{
DisplayName: myself.FullName,
Claims: "i:0#.f|membership|" & myself.Email
},
Parent.Default)
And for the Line Manager field I'm trying to populate
Items:
Choices([@AUGBE_TEST].Line_x0020_Manager)
DefaultSelectedItems:
If(DataCardValue12.Value=false, {'@odata.type':"#Microsoft.Azure.Connectors.SharePoint.SPListExpandedUser",
Claims:"i:0#.f|membership|" & Office365Users.ManagerV2(DataCardValue28.Selected.Email).mail,
Department:"",
DisplayName:Office365Users.ManagerV2(DataCardValue28.Selected.Email).displayName,
Email:Office365Users.ManagerV2(DataCardValue28.Selected.Email).mail,
JobTitle:"",
Picture:""
})
None of the properties' syntax are in error but when I publish the form I get the following error in the form in the person column;

I have no idea what's causing this or how to fix it. Has anyone else run into this issue before?
Any ideas on how to fix this?
Any help would be greatly appreciated.
