Type name is null in introspection when using Type::listOf

[dmongeau]

As described in the issue folkloreinc/laravel-graphql#50 the type name is null when using listOf.

Query:

{  
  __type(name: "User") { 
    name 
    fields { 
      name 
      type { 
        name 
      } 
    } 
  } 
}

Response:

{
  "data":{
    "__type":{
      "name": "User",
      "fields":[
        {"name": "followings", "type":{"name": null }},
      ]
    }
  }
}

I suspect this is because public $name is not set in the ListOfType. It may be setted in the constructor. I can submit a pull request if it makes sense.

It is not a bug. ListOf and NonNull are not named types (their name is null). Instead wrapped type is stored in ofType field.

Change your query to:

{  
  __type(name: "User") { 
    name 
    fields { 
      name 
      type { 
        kind
        name 
        ofType {
          name
        }
      } 
    } 
  } 
}

and you will see what I mean.

If you try graphql-js at http://graphql-swapi.parseapp.com/ and run the same query against any type containing nonNull or listOf field - it will return the same result.

Also I am curious where do you use this?

Ok I understand, sorry about that! Actually, it's not coming from me. Someone as filled an issue on laravel-graphql.

No problem! %)
