{"error":{"code":"","message":"Value cannot be null.\r\nParameter name: source"}} #369

I am trying to use the reference service https://services.odata.org/TripPinRESTierService form Salesforce, and the Airlines and Airports works well. But when I try to access the Person Object, I get this error:

{"error":{"code":"","message":"Value cannot be null.\r\nParameter name: source"}}

This is the query that is being made.

https://services.odata.org/TripPinRESTierService/(S(y5p3g0acttyshhhmucgq5fvb))/People?$filter=UserName eq 'angelhuffman'&$count=true&$select=AddressInfo,Age,Emails,FavoriteFeature,Features,FirstName,Gender,HomeAddress,LastName,MiddleName,UserName

I am assuming the primary key of that object is the Username.

This error occurs because the Features property for angelhuffman is not initialized in the data, so it is null which is not allowed for a collection-valued property.

A simpler repo would be: /People?$select=Features

Fixed by https://github.com/OData/ODataSamples/pull/223. Just needs to be deployed to services.odata.org.
