Why is generic-auth adding @ to list?

[VilleViktor]

Hello community!

Why is generic-auth changing the resulting data by adding @ to list? More specifically here.

if (isListType(field?.type)) {
  resolvePath.push('@');
 }

Changing the path on the data, resulting in :

{
 "data": {
   "@": []
  }
}

which seems a bit weird. What is the reason?

Also to be noted, is that if the list is

  type: GraphQLList {
    ofType: GraphQLNonNull { ofType: [GraphQLObjectType] }
  }

it will replace the path with "@", but not when the type is:

GraphQLNonNull { ofType: GraphQLList { ofType: [GraphQLNonNull] } },

Im having a hard time understand why someone want to replace the paths?
