Expected Results

Actual Results

I get a crash when try to filter a result

*** Terminating app due to uncaught exception 'RLMException', reason: 'Object type '(null)' not managed by the Realm'

Code Sample

I have next class

final class Contact: Object {
  ...
  let additionalCompanies = List<String>()
  ...
}

And I try to filter a result using the next code:

let res = realm.objects(Contact.self).filter("SUBQUERY(additionalCompanies,$element,$element.stringValue == %@).@count>0", "something")

I could make a mistake in the predicate, but the exception is strange of me in this case.
