  }
}

Inside the User selection set, add the field id to fetch the user's ID.

GraphQL

query GetUser {
  User {
    # Add the id field here
  }
}

Need a hint?

Simply add id inside the User braces.

Add the name field

Add the field name inside the User selection set, below id.

GraphQL

query GetUser {
  User {
    id
    # Add the name field here
  }
}

Add name just like you added id.

Finally, add the field email inside the User selection set, below name.

  User {
    id
    name
    # Add the email field here
  }
}
