Filtering objects with null property on Realm for React Native

React Native and Realm noob here!

I want to load objects where one particular property is null.

I tried to filter them like this:

let goals = Modal.objects('goal').filtered('SubGoalOf == $0', null);

I've also tried this:

let goals = Modal.objects('goal').filtered('SubGoalOf == $0', {});

But got errors like "Value is not an object" and "object is not Realm Object". Query without filtered method is working perfectly and returning everything. But that's not exactly what I am going for.

This would be the schema:

Goal.schema = {
  name: 'goal',
  primaryKey: 'id',
  properties: {
    id: 'string',
    createdOn: 'date',
    itemName: {type: 'string', indexed: true },
    SubGoalOf: {type: 'goal', optional: true},
    ShouldNotify: 'bool',
    WhenNotify: {type:'date', optional: true},
    deadline: {type:'date', optional: true},
    isComplete: 'bool',
    completedOn: {type:'date', optional: true},
  }
}

It would be great, if anyone could help me. Thank you.

Currently, Realm React Native doesn't support querying for null. This enhancement is tracked by this issue:

Implement/test null queries for all optional types
