Får error 400 i begge tilfeller, dessverre. Uten '' er feilmeldingen i tillegg Possibly unhandled rejection: {"data":{"error":{"code":"","message":"Could not find a property named 'Nan' on type 'NorthwindModel.Employee'. Om jeg legger til '', blir feilmeldingen Possibly unhandled rejection: {"data":{"error":{"code":"","message":"An unknown function with name 'substringof' was found. This may also be a function import or a key lookup on a navigation property, which is not allowed." i tillegg til error 400. :/
