Hello, when I use @auth directive, the erorr will throw. When I delete it, graphql query work well.

Graphql schema

type User {
	id: ID @id
	username: String! @unique
	firstName: String!
	lastName: String!
	email: String!
	password: String! @private
	roles: [Role!]! @relationship(type: "IN_ROLE", direction: OUT)
}

type Role {
	name: String #read:Blog, write:Catogory
}

type Mutation {
	signUp(username: String!, password: String!): String! ### JWT
	signIn(username: String!, password: String!): String! ### JWT
}

extend type Role @auth(rules: [{operations: [READ], isAuthenticated: true }])

My query

query{users{username roles{name}}}

The eorror
