When you mark a field as @id, it the AddXInput will have the field but the UpdateXInput will not. How do you update an @id field?

> You can update the data using a DQL mutation. If you don’t have the uid mapped in GraphQL using ID then you can do an upsert using your field with @id. type User { username: String @id isActive: Boolean } upsert { query { user as var(func: eq(User.username,"foo")) } mutation { set { uid(user) \<User.username\> "bar" . } } }
