Using empty input object value

[luigi-yoon]

Hello,

I am a new user.
This issue may be a duplicate issue.

In Graphql Voyager, if you click the root type when there is an empty input type in the schema, an error occurs.

---

type Query{
	pizzas(filter: pizzaFilter = {}): Pizza
}

type Pizza{
  name:String
}

input pizzaFilter {
  name: String
  next: Int
  total: Int
}

---

Probably because of this. (pizzaFilter = {})
This error does not happen when empty input object is not the default.

type Query{
	pizzas(filter: pizzaFilter): Pizza
}

type Pizza{
  name:String
}

input pizzaFilter {
  name: String
  next: Int
  total: Int
}
