Hello,
I'm trying to create a Dataverse database & accompanying Power App to manage basic course information. One of the fields (columns) in the database (table) is 'Course coordinator':

For the 'Data type' I had selected the 'Customer' value, because (while our course coordinator is a colleague and not a 'customer') it was the only 'person' data type in the list.
In my app I use the following for the Items. I can search and select users without problem
Office365Users.SearchUserV2({searchTerm:DataCardValue4.SearchText,top:5}).value

However, when hitting the Save button, I get an error saying that a required field is not filled.

The field is required in the database and in the app, but somehow the value does not seem to bet stored.
The OnSelect of the Save button is simple:
SubmitForm(FormNewCourse)
Would I need to do anything extra to take and 'store' the value (person) in this database field? Or is the 'Customer' field/data type not the right one for this purpose?
