Hello,
i have a strange problem that has never occured to me.
I am trying to Update some SPO Person Columns but i get this error

My Patch for my person columns looks like this.
I have also tried it without the O365 Lookup because im useing a Combobox with O365 Datasource. Still doesn´t work.
'Project manager': {'@odata.type': "#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference",
Claims: "i:0#.f|membership|" & Lower(LookUp(Office365Users.SearchUserV2().value,DisplayName = Responsible_Input_1.Selected.DisplayName).Mail),
Department: "",
DisplayName: Responsible_Input_1.Selected.DisplayName,
Email: "",
JobTitle: "",
Picture: ""},
Calculant:{'@odata.type': "#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference",
Claims: "i:0#.f|membership|" & Lower(LookUp(Office365Users.SearchUserV2().value,DisplayName = Calculant_Input_1.Selected.DisplayName).Mail),
Department: "",
DisplayName: Calculant_Input_1.Selected.DisplayName,
Email: "",
JobTitle: "",
Picture: ""},
Pers_Div: Members,
'Key account manager': {'@odata.type': "#Microsoft.Azure.Connectors.SharePoint.SPListExpandedReference",
Claims: "i:0#.f|membership|" & Lower(LookUp(Office365Users.SearchUserV2().value,DisplayName = KAM_Input_1.Selected.DisplayName).Mail),
Department: "",
DisplayName: KAM_Input_1.Selected.DisplayName,
Email: "",
JobTitle: "",
Picture: ""},
Did i misspell something?
