OperationContext contains empty variables for variable with query

[khumps]

What happened?

setting up the following for the handler

srv.AroundOperations(func(ctx context.Context, next graphql.OperationHandler) graphql.ResponseHandler {
		oc := graphql.GetOperationContext(ctx)
		fmt.Printf("%+v", oc.Variables)
		return next(ctx)
	})

prints map[] on the following query

query Query {
  genConfigJson(id: 1234567)
}

The query succeeds and returns data in graphiql

What did you expect?

the print statement should have printed {"id":1234567}

Minimal graphql.schema and models to reproduce

scalar Map

type Query {
  genConfigJson(id: [Int!]): [Map!]
}
