Realm one-to-many relationship with _id foreign_key and array of objectIds not working for graphql

Okay so I want one collection to have a field with an array of objectIds that point to another collection. The objectids are the _id field on this other collection.

The problem is it doesn’t work.

this is the relationship.json file on the one in the one-to-many relationship

{
  "businesses": {
    "ref": "#/relationship/occasionally-business-db/Business/Businesses",
    "source_key": "businesses",
    "foreign_key": "_id",
    "is_list": true
  }
}

And then here is the schema on that collection:

{
    "properties": {
        "_id": {
            "bsonType": "objectId"
        },
        "userId": {
            "bsonType": "objectId"
        },
        "businesses": {
            "bsonType": "array",
            "items": {
                "bsonType": "objectId"
            }
        },
        "createdAt": {
            "bsonType": "date"
        },
        "updatedAt": {
            "bsonType": "date"
        }
    },
    "title": "AdminAccess"
}

Interestingly, if I use a string field on the business collection, which is the many in the one-to-many relationship, it does work. Seems like it should work in this case. What am I missing?

And when I say it doesn’t work, I mean it doesn’t work for graphql.

I am trying to query like this:

query {
  adminAccess {
    _id
		createdAt
		updatedAt
		userId
    businesses {
      name
    }
  }
}

but businesses returns an empty array even though it shouldn’t. Has anyone had this problem?

Thanks!
