I bet People displays a person name, but it is pulling data from the exchange server so I bet it is actually storing some kind of exchange ID. So I would think it is a kind of lookup field.

Yes, that's why I was being nitpicky. It refers to someone in that SharePoint tenant. If it is a required field, and I think that's optional, then that might account for the error.
