context[:current_resource]が使えないなぜ？(undefined local variable or method `current_user')

Question

graphql-deviseを導入していますが、下記のよう設定をしてもcontext[:current_resource]を使えません
なぜでしょうか・

configration

自分のschemaにdeviseを導入しています。

class MySchema < GraphQL::Schema
  use GraphqlDevise::SchemaPlugin.new(
    query:            Types::QueryType,
    mutation:         Types::MutationType,
    resource_loaders: [
      GraphqlDevise::ResourceLoader.new('User'),
    ],
    authenticate_default: false
  )
  mutation(Types::MutationType)
  query(Types::QueryType)

  # Setup GraphQL to use the built-in lazy_resolve method
  use BatchLoader::GraphQL
end

route.rb:

Rails.application.routes.draw do
  # For details on the DSL available within this file, see https://guides.rubyonrails.org/routing.html

  # For graphql
  if Rails.env.development?
    mount GraphiQL::Rails::Engine, at: "/graphiql", graphql_path: "/graphql"
  end
  post "/graphql", to: "graphql#execute" 
  get "/graphql", to: "graphql#execute" 

graqhql_controller.rb:

def execute
    variables = ensure_hash(params[:variables])
    query = params[:query]
    operation_name = params[:operationName]
    result = BusinessCloudSchema.execute(query, variables: variables, context: graphql_context(:user), operation_name: operation_name)
    render json: result unless performed?
  rescue => e
    raise e unless Rails.env.development?
    handle_error_in_development e
  end

user_update_input.rb

module Types
  class UserUpdateInput < Types::BaseInputObject
    argument :fist_name, String, required: true
    argument :last_name, String, required: true
    argument :position, String, required: false
    argument :image, ApolloUploadServer::Upload, required: false

    def update!
      current_user = context[:current_resource]
      current_user.assign_attributes(first_name: first_name, last_name: last_name, image: valid_image)
      current_user.update
      {
        errors: user_errors(current_user.errors),
        user: current_user.reload
      }
    end

    private

    def valid_image
      image if image&.is_a?(ApolloUploadServer::Wrappers::UploadedFile)
    end
  end
end

update_user.rb

module Mutations
  class UpdateUser < BaseMutation
    field :user, Types::UserType, null: true

    argument :user, Types::UserUpdateInput, required: true

    def resolve(user:)
      {
        user: user.update!
      }
    end
  end
end

下記クエリを実行しても動きません。

mutation{
  updateUser(input: { clientMutationId: "", user: {fistName: "aa", lastName: "bb", position: "manager"}}) {
    clientMutationId
    user{
      email
      firstName
      image
      lastName
      position
    }
  }
}

context[:current_user]としてもnillになります。
