GIVEN

The following schema:

{
    "properties": {},
    "scripts": {},
    "fieldsInLists": [],
    "fieldsInReferences": [],
    "fields": [
        {
            "name": "array",
            "properties": {
                "fieldType": "Array"
            },
            "partitioning": "invariant",
            "nested": [
                {
                    "name": "nullableProp",
                    "properties": {
                        "fieldType": "String",
                        "editor": "Input",
                        "contentType": "Unspecified"
                    }
                },
                {
                    "name": "ref",
                    "properties": {
                        "fieldType": "References",
                        "editor": "List"
                    }
                }
            ]
        }
    ],
    "isPublished": true
}

Current behavior

When run the following GraphQL query, I get an unexpected result, where null values are converted to string, as so:

Expected behavior

The expected result would be for null strings to be returned as null. Not as a string
