Gateway query fails if a type is redefined

[codeflyer]

Hi,
I'm facing this issue using the gateway feature:

I've 2 nodes that declare the same type, it's a wrapper to normalise the return list:

    type PageInfo {
      edges: [User]
    }

The first node declare and resolve the User type

  extend type Query {
      me: User
    }

    type PageInfo {
      edges: [User]
    }

    type User @key(fields: "id") {
      id: ID!
      name: String
      username: String
    }

The second one has a query that return the list of the users:

    extend type Query {
      meWrap: PageInfo
      meWrapDifferentName: PageInfoRenamed
    }

    type PageInfoRenamed {
      edges: [User]
    }
    
    type PageInfo {
      edges: [User]
    }
    
    type User @key(fields: "id") @extends {
      id: ID! @external
    }

The query that uses the type with a diffrent name, works properly as expected:

   {
        meWrapDifferentName { edges { name }  }
   }

Instead the query that used the type that's declared in the other node as well fails:

   {
        meWrap { edges { name }  }
   }

with the error:

Cannot query field \"edges\" on type \"Query\".

A test file that replicate the issue is available here:

Can you please make a reproducible example?

I don't understand why you are redefining the type.

[mcollina]

Why are you not using the @external directive on edges?

I-ve created a test in the PR in the comment, this the direct link to the file:
