      Reproduction Steps

      Realm Sync

      I'm using partition sync.

      The code for reproduce this error is

      useEffect(() => {
    const formsResult = realm.objects("Form");
    console.log(formsResult.toJSON());
    console.log(JSON.stringify(formsResult)); //also doesn't works
    
  }, []);

      My model file is configured like the code bellow:

      class Form extends Realm.Object {
  _id?: Realm.BSON.ObjectId;
  _partition: string;
  active?: boolean;
  author?: Author;
  name: string;
  sections: Section[];
  createdAt: Date;
  updatedAt: Date;

  static schema: Realm.ObjectSchema = {
    name: 'Form',
    properties: {
      _id: 'objectId?',
      _partition: 'string',
      active: 'bool?',
      author: 'Author',
      name: 'string',
      sections: 'Section[]',
      createdAt: 'date?',
      updatedAt: 'date?'
    },
    primaryKey: '_id',
  }
}
