Fragment cannot be spread here as objects of type "_Entity" can never be of type "X"

Hi everyone! From apollo-server v 2.8.0 we are able to use same Value Types in multiple services: https://www.apollographql.com/docs/apollo-server/federation/core-concepts/#value-types

As an example I experimented with federation-demo: https://github.com/apollographql/federation-demo

I’ve added object type (Logs) in account service:

extend type Query {
  me: User
}

type User @key(fields: "id") {
  id: ID!
  name: String
  username: String
  logs: [Logs]
}
type Logs {
  id: ID
  message: String
}

and the same type in products service:

extend type Query {
  topProducts(first: Int = 5): [Product]
}

type Product @key(fields: "upc") {
  upc: String!
  name: String
  price: Int
  weight: Int
  logs: [Logs]
}
type Logs {
  id: ID
  message: String
}

all project is compiled successfully and now we may use one object type (Logs) in multiple services (according the rule of value types in federated service is that the types must be identical in name and contents):

But when i try to prepare data for logs property:

const users = [
  {
    id: "1",
    name: "Ada Lovelace",
    birthDate: "1815-12-10",
    username: "@ada",
    logs: [
      {
        id: 1,
        message: "Some Message"
      }
    ]
  }
];

I got the following error:

            ]
          }
        }
      }
    }
  ],

Is it a bug or I’m doing something wrong?

@sgarciac the fix should be merged and released in 2 days or less. In simple cases, renaming the types locally per service can function as a workaround - and in the case of input types as you noted, this should certainly work.

Does anyone have a workaround for this issue while waiting for the bug fix? federating services that use the same value types is fairly common (for example, for pagination), so this is quite blocking D:
