Federation and Node interface

[theprobugmaker]

What happened?

I'm trying to use the Relay Connections specification for pagination with gqlgen + entgo (from this tutorial: https://entgo.io/docs/tutorial-todo-gql-node) but when I create an interface Node that the type User implements, I'm getting an error.

merging type systems failed: unable to bind to interface: poc/ent.User does not satisfy the interface github.com/99designs/gqlgen/plugin/federation/fedruntime.Entity
exit status 1

What did you expect?

I need the Node type to work with the Relay Connections specification.

Minimal graphql.schema and models to reproduce

interface Node {
  id: ID!
}

type User implements Node @key(fields: "id") {
  id: ID!
}

versions

• gqlgen version? 0.16.0
• go version 1.17

You have to create a function called IsNode on your User model
If you need to resolve entitites with federation, you need to add IsEntity as well

func (User) IsEntity() {}
func (User) IsNode() {}
