GraphQL query polling returns null node

[annapurna]

Why does GraphQL Bulk Query return the following response for an operation?

{
            "data": {
                "node": null
            },
            "extensions": {
                "cost": {
                    "requestedQueryCost": 1,
                    "actualQueryCost": 1,
                    "throttleStatus": {
                        "maximumAvailable": 2000,
                        "currentlyAvailable": 1999,
                        "restoreRate": 100
                    }
                }
            }
        }

 Node is `null` no matter how many times it is tried.

It's difficult to ascertain without seeing the GQL request you are making. Can you provide that?
