> I have JPA-Entity "User" and I try to return it with FunctionImport:
> @FunctionImport(name = "myFunc",entitySet = "User", returnType = ReturnType.ENTITY_TYPE , multiplicity = Multiplicity.ONE, httpMethod = @HttpMethod(name = Name.GET))
>   public User currentUser(){
>          User currentUser = getLoggedInUser();
>               return currentUser;
>   }
> But the response  from that function is:
> <error xmlns="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
> <code/>
> <message xml:lang="en">
> An exception of type 'NullPointerException' occurred.
> </message>
> </error>
> I have tried to chage the ReturnType and Multiplicity but the response was same. 
> For example If I re-factor the function to return Integer and set the Return Type to SCALAR it works fine.
