@paulrostorp romshark 's case is different. He is using GraphQL Variables (a concept imported from GraphQL). You can open another ticket for this, cuz this implementation is totally different. But please, first check if there isn’t any other issue already on this topic.
Unless the case is a mix of both features. And the GraphQL Variables works fine on this case. I remember someone working on something related to GQL Vars a year ago, not sure.
Cheers.
